The intensity is good, and I like the way you've composed this. The lighting (underexposed) and contrast (flat) could use a little work IMO. Good luck in the challenge.
i see what you trying to get at, but a shot like this really needs some intersting lighting, cause this is super flat, and you need it to be SHARP...sharp so you but yourself on it. It;s not sharp it simply looks like you forgot to do it, and i mean....it's digital. you can retake the shot if need be.
Wow, this shot has a lot of depth to it on several fronts. I'm just wondering if perhaps a bit of lightening and contrast adjusting might have brought this out a bit more. The expression is one that's "harsh" looking, so lighting being a bit harsher might have brought that out a bit more????
Wow, whatever your ying yang is, I don't want to touch it. (In other words, title distracts from what otherwise is a very strong photo with interesting lines.)
