This is an interesting composition, but it also seems to be one that needs some sort of context other than what is provided to make it more interesting. When photographing people for a challenge, (or for anything in fact) you need to create something that helps a third-party viewer identify with your subject in some way. You need to make me interested in who I see. As far as your post processing is concerned, if you achieved what you wanted, it's fine. The color hues here are a bit strange for me. The skin tones don't seem normal and there is a blue/green cast throughout the rest of the image, including his hair. There is nothing wrong with doing things this way, but they need to serve a visible and identifiable purpose when posting them for public review most likely.
Well, it's not your score, that is down here. :)
Just kidding - just yankin yer chain. This is an interesting composition, but maybe cut too much of him out. Good focus and I like the colors and textures. Good luck.
The border is distracting and I think for this type of composition you need to include his whole face. There's something uncomfortable about not seeing his ear and chin.
The hue is a bit too green for my tastes, and I'm not sure that I like the missing chin/ear. Good repetition of textures between his facial hair and the wall.
Nice and clear image although the person blends a little into the background...
Átt þú eitthvað í þessum kalli Lára? Nú kannast ég við hann af hattamyndinni....
I like the composition of this shot. It does seem to be a little washed out and to have a slightly green caste, but that's easy to take care of. Nicely done.
