Finally I have access!
Most of these writing tips I endorse, especially the lovely lines about characterisation. I ALWAYS create a detailed picture of my characters that doesn't stop at their eye- and hair colour. To grab their personality, I use to ask: what car are they driving?
Yes, yes, along comes Venom with his car fetish; but for most people the choice of car is an emotional and therefore personal act (let us pretend that money is irrelevant in this case).
Furthermore a good characterisation helps to prevent repetitions: beside the character's name terms like the girl, the blonde, the Italian are at disposal.
The words about the dialogue: absolutely true! It's a powerful tool to tell and to "break open" longer passages. I also like to give the characters unique phrases or a specific style of talking. Ideally the reader detects who is speaking just by this. For example I let a person use a term or a short phrase from her/his native language, without translation. A direct translation would only disturb. Therefore it is necessary to give a clean context, like: "Hola," he greeted. No need to understand Spanish...
The part about the sequels doesn't give much to me. At every point of my stories I have a rather clear idea what and how to tell the reader - mostly intuitively.
I also never had a problem to create a plot. My head is full of central ideas, and for a clean structure I'm follow H.P. Lovecraft's technique: two detailed plot/chapter lists, the first with all parts in the order they are happening, the second one with all parts in the order in what they will appear in the story. But the most important item is the total freedom of changing these orders whenever it is necessary.
The Deadwood part is written just for me: my weakest point is using much too many words. Not that I'm a fan of endless sentences - no, I even love strong single terms. But the text must provide precision; I'm just not happy to count on the reader for understanding a sloppily written scene.
I think that's it. I don't see myself as a great author, at least not in the extent my text above could suggest. But I'm good enough to know that I can - and have to - learn a lot more...
