Critique this excerpt please? It won't be too painful I promise.?

Why not write the whole story? It's a nice start and flows well. Now is not the time to start editing. The old saw is write fat, cut later. Otherwise, you'll get snagged in the bushes when you should be covering the whole forest. I'd like to find out what happens to your character. And at this point that's all you really need in terms of criticism.
