Though the colours and the style really reminds me of the old Assassins Creed game, I can't help but point out that the fingers look unnatural. But what I do like though is how you didn't completely rip the armour straight from the game and copy it onto your art. Also, I know what you tried to do, cover up the eyes with the hood, or at least make the shadow cover his eyes. But if you tried to make the shadow cover his eyes, you should have made it darker. Looking at his face seems like a real error, because it shows he has no eyes. (Unless his eyes are on his forehead, but I doubt it). Overall, I like what you did, but it just needs some fixes. Keep it up.
I might draw an update of this and fix the errors you pointed out. Thanks for reviewing this and letting me know what I can do to make it better.
