Initial Impact: Freaky, creepy, cool, I like it!!!
Contrast: This photo has it in spades!Lots of wonderfull contrast.
Composition: The flower seems cramped. I think a little looser crop or eleimation of the border would help this image breath a bit.
Focus: Looks to be a pretty sharp image, but towards bottom center of the flower there is a grey "tongue" it looks to be OOF I think this is more because of texture than focus. But it still "appears" to be slightly OOF. Otherwise nice crisp image with a smooth solid edge.
Overall: This is a pretty good shot but I feel it could be greatly improved by giving it breathing room. As t sits now it feels a bit too "in your face" to enjoy as it should be.
I'm giving this photo a 10, but I think it needs a little more breathing room between the edges of the subject and the border. It's a bit cramped... it does make an excellent b/w though.. nice work :)
