the screenshot isn't huge, it's a good size.

if it would be fallen, it would have a pale tint, not a demon tint. is it nescesarry to say hellscream did, so he cannot be any demonic?
I'd like to say it's a nice skin, i'd rate it 2,7/5, but not 3/5, beceause of the following reasons;
you should fix him face, his eyes are too crushed against other, his nose is too big, mouth too undetailed, try doing like the orc on warcraft 3 when you start the game theres a yellow-green orc with yucky teeths yknow..
nice effort on the pants, but those stitches looks bad, they aren't thick-looking enough, basicly it just looks like you did one line and left it like it is. also try to shade it so it looks like silver, after all you have set it to a bigger resolution, no?
good chain effects on its gloves, now they look like thick, good job here, but on the screenshot it looks like very horrible. but on the uv map wow!
add more colors, its mainly black and red now, pretty harassing for the eyes.
it's a decent skin (2,5+/5 = decent), im sure some people could use it, but it's not over, continue working on it if you think its not nescesarry. and i hope with the next skin you'll receive a bigger ranting from me (perhaps 2.8 or 2.75), beceause no one has reached 3, 4 or 5 yet, even tho i have 100 comments on skins and icons and 3 art and 2 model.
cheers, don't forget to fix the face, its a major point here, and don't leave so many black space, fill it! add more definition but keep it clean. don't overuse smudge, in these situations it looks like bizzard and its really easy to guess you used smudge.
cheers.
