Hey there! I wanted to let you know that I've seen this and intend on getting to a complete rip of it as soon as time allows. Just in case thigns get out of hand for me, I wanted to throw a couple things I saw right off. So, here ya go!

Steve stood outside the metal door, waiting, running his hand through his short, dark hair. There was nothing else to do. The door in front of him was as innocent of a doorknob as the one behind him. And the blank white walls offered no distraction.
This still falls flat. It is a little too simplistic and you seem to be over explaining. When I get the chance I will try to help you with a few changes - a few ideas. It's a matter of order and combining of ideas that is my complaint, really.

He knew he shouldn’t get angry. Anger was a luxury he couldn’t afford. Accepting his situation was the only option that made any sense. But Steve knew that this delay was intentional, and he resented it. He was aware of his status; there was no need to remind him this way. His belly roiled as his mind skittered down the well-worn and useless paths. Discouraged, he wondered if he would ever reconcile himself to his situation. Finally, with a skill born of long practice, he schooled himself to patience.
You over explained here. Also, the notion that any option, in his situation, would make sense or not is immaterial. Again, I will try to give you a bit more. But you over explained these things and you weren't quite cut throat enough in them. What options did he have? What could he afford to feel? You gave him too many choices. Cut it down!
