Wrong number of horns, wrong number of ears, the sword would snap with use being that broken, the face is wrong, the right hand is horrid... The art style is like that done for the game, so.. that's nice. Also nice floaty chains on the armor.
ah now i see it, wow, nicely hidden by the way i dont think its the hardest, just put down the basic shape of how you want you chain to look like in a dark color (or black/dark grey), then add highlights of where the light comes from
hmm. Looks great, but a few minor issues I have; 1. Charr males are far more burly than that- if you look at most pictures of them, their torsos are at least twice the width (dorsal-ventral) of their arms, they aren't just fuzzy Norn. 2. His jaw bugs the crap out of me for reasons I just can't place. Maybe it's how round it is in the back.
But yeah, other than those two things, it looks great. Taken out of context, he looks like a lean, green, stabbin' machine in the art style of GW2.
RE: 1. Well, actually there are builds available in the character creator that are pretty much like in this picture. Not every male charr is burly, just as not every asura is thin. For a real charr, the guy up there should be hunched over a little more, though ...
