Ambiguity, thank you for your paintover, and yes, you are certainly right, I should've do something with his left hand

And I agree about rim light - there is no explanation of it. When I made it I thought it can be the light from the monitor, but then it should be more frontal (if it's a right word) than right now.
C Bear, thanks

Tear in the sleeve should've represent some energy of gesture according to my plan. And anyway this actually happens time by time ^_^'
Fenix_N, thank you. Frankly, I can't answer why exactly there's blues and greens in the background. When I choosed "angry color" for the character I tryed to make the background more contrast to him.
So yes, I think I could say, it's to pop out the character. But maybe (and probably) it's not the best colors. I'm still not any good with picking the right ones.
Byfield, ha, it's a really good idea to grab his hair with his left hand - definitely I should've draw something like this! Well, I hope I'll dream up something like this next time. Thank you for appreciation!
