Congrats on a top ten! Very much within the guidelines of "how to score well at DPC" - clean, uncluttered composition, great light, clearly identified subject. Good work!
The old dirty hand. As a pretty good shot that maybe could have benefited from a little bit more dramatic lighting. The effect seems a little flat. Everything's well lay it however the lack of shadows doesn't really present what the image might be trying to say.
This is great- I've seen something like this somewhere before- I know I have; and it still grabbs my attention and makes me go "WOW" - sharp focus, beautiful high-key background, it doesn't even need a border because the subject pulls you right into it! :) -~~10~~ !
