I thought I'd join in the fun, here. Thanks for offering us the opportunity to tear you to shreds!
Agree, it doesn't work.
I think you need a few more commas in both of these sentences. 'of an older generation' is a sub-clause that could be removed from sentence without damaging its make-up: one of the things I was taught long ago is, capture those gramatically unnecessary sub-clauses between commas.
You have a possesive apostrophe missing.
I see it as:
A tall woman, of an older generation, stood over what appeared to be a marble statue depicting a nymph pleasuring two satyrs. Smiling, she bent down and peered into the nymph's closed eyes and whispered something.
I also don't like 'and peered (...) and whispered'. I would prefer 'and peered (...) whispering or '...eyes. She whispered...'
Admittedly, that would give you a repetition with the next phrase, but I'm sure you can fix that!
She is whispering, then she is talking to Francis, obviously out loud. I just feel you need a transition between the two - say, she turns, she stands up, she raises her head, some activity that allows the change in volume to be natural from the beginning of her sentence, as opposed to the reader having to realise it. I recognise that the fact that she says 'Francis' first does this - but I don't know, I would prefer
'Francis,' she called,
or something like that.
Repetition of 'this one' and 'man'. Prefer
"Ah... that is my most recent piece," Francis said, striding over to him.
Or such.
Mix of singular/plural.
Yes, I know - there is debate about the use of commas with 'but' and 'and'. Personally, I believe this has now become normal usage, and it makes the sentence read better.
There's a space missing in "rather...well"
It doesn't really matter, but is 'the man' Francis - her captor - or the guest?
'gallery of people' seems overkill. How about just 'the room'. I know rooms don't laugh, but it's a well-known form of speech!
"related"? Really?
Minor nit-pick - she's his latest creation, is it really 'many a night'? I like the phrase, it is perfectly Francis. It just may not be true.
OK, I have real problems with this. This is a normal height desk, yes? How does he get his knees under the desk, given that desks are designed to be just the right height, but now he's got a body in the way? Does he? Is he going to kneel on the floor behind her - doesn't sound comfy enough for him!! - how does this work? I find it very confusing, I can't picture it properly.
Maybe it doesn't matter, after all, I get the idea - but I think the idea has to work, and I'm not sure it does.
But I'm not gifted at visualising things, so it may just be me!!
For some reason, 'bottom' just doesn't sound right in Francis' mouth here (if you see what I mean!!). I feel he would use a colder, more medical term, anus, probably.
'ensconced' takes 'in', I think?
'make your way' is more usual than 'make your path'
'retort' is the wrong word. As per dictionnary.com, retort means:
1. to reply to, usually in a sharp or retaliatory way; reply in kind to.
2. to return (an accusation, epithet, etc.) upon the person uttering it.
3. to answer (an argument or the like) by another to the contrary.
Get rid of 'rather'? Or use a more Francis-like word - e.g. 'adequately' - a sense of tittering relish and innuendo being brought in...
Why? What is special about this synthetic material? Either this needs expanding, or removing.
"Interesting,"
Should there be an exclamation mark, then?
'if you don't mind' isn't quite Francis, either - he's not the sort to be apologetic, even when being a polite host, is he?
'if you are ready', maybe?
and 'get to serving' - especially so soon after 'get started' - don't like that. How about 'so she can start serving us.'
'in grand words' - well, I think I know what you wish to convey, but I'm not convinced you are conveying it. They are being effusive, complimentary, are they not? 'grand words' just means they're a load of intellectual pedantic pricks discussing art-work; which of course is also an aspect.
Oh, woops, did I sound like I didn't like them there for a minute?
in a quest to discover... no... don't like that... 'eager to discover' I would prefer, or such.
And - careful - here you say 'most' - see notes later re the creator.
OK, the introduction and 'un-noticed' presence of the artist, these really bother me. He is obviously a twisted genius, and wishes to remain private. It doesn't strike me that he would sit in the room with them, have dinner with them, if he wished to retain the right not to be introduced to them. I would have thought it sat far more in the vein of things that he should be observing them unseen. He should communicate with Francis in some way or another before the introduction, to indicate to Francis that he is willing to be introduced. This communication should be discrete enough to be unobserved by the guests, or at least, it should not raise their interest particularly. Otherwise, Francis is quite possibly introducing the artist when he actually has not gained the confidence in these people that he wishes.
Could someone be expulsed, on his request? Anyone who wasn't actively asking how they could get such a piece, for example? (ref. 'most')
This could be more descriptive of the eager tension they are feeling.
repetition of enjoying
repetition of the man
For some reason, 'fist' sounds wrong
Sounds too much like Francis. I think he ought to sound more like a boffin; shy mad professory type, obsessed by the methods he uses and his research; or, like a pretentious artist, waffling on about the intrinsic symbolic significance of his works and the message they bring to the world. Either one would give him the capacity to be enthused by what he does, in a way that avoids the actuality of his own sadism. His clients are sadists; he is a creator.
There! I have been unashamed in voicing my opinion, to the point where I'm shoving my nose in where it's not my business, I think - not just points of style or nit-picks. But I did enjoy doing it, and you're right, doing this helps one to think more consciously about one's own writing.
So thanks again for the opportunity.
