The way the hair is lit makes it look like it's in an epicly
huge pompadour and also makes the skull seem larger than what the face would suggest.
The fabric on the clothes look badass as hell. Really good. I'm hoping this dude is some kind of suave villian.
This is what I mean about the head (amateur photoshop liquify incoming)
I asked an artist friend of mine about the pic and will paraphrase him here. He reckons it could do with some contrapposto*. In this case the right shoulder should come down and the left up. Swap that angle and probably shift more weight onto that back foot so the nose is more over the heel.
He also said it's hard to tell what's happening at the knee area of his right leg. With clothing the lines should come from where the tension is happening so it's almost right, but as it is, it doesn't help define the form underneath.
Could drop the nose down an little, the proportions from eyes to nose to mouth to chin are a bit off - they seem all equal.
The left arm disappears, can't tell where it is or what it's doing.
