I didnt really notice anything too bad about that bit. There was one problem that struck out at me, but im not sure if that is entierly due to your writers block.

Watch your tenses. In the first few sentances, then through the whole chapter, its constantly switching, and you got to be careful.

Aside from that, its darn good. But I know what you're feeling, I think its Writers Block season. I'm also suffering from the same thing, and put the first chapter up of my fic in a bout a month, and I'm not happy with that. But just remember, something will come along and jolt you out of writers block, its happened to me. Perhaps you need to take a break and write something short and fresh to get your mind flowing again.
