The second one is interesting, I enjoyed all of the texture and repetition of the windows... Too bad about your friend's tooth. See what he gets? Remind me not to sneak up behind you!
I like both of them. These are the kinds of subjects I'd like to get into. Combining them with available lighting creates a lot of drama to the photos.
In your photos, I like the way the eyes move from one side of the picture to the other. Nicely done.
