I like the first one a lot. The second one doesn't do much for me because I really don't know what to focus on.
I love the third one and I would kind of like to see it in color -- even though I know that wasn't your intention.

WOW! I freaking love this shot. Before anyone hollars out "Rule of Thirds", I think this is perfect centered. Here's a vignette I think works well. :thumbup: Nice job!
