the text doesn't work with the sig on this one for me personally and your light source seems to be off and looks too sharp at the bottom of it the depth seems to be lacking with the darker areas for me as well not trying to be picky bro just calling it as im looking at it i like the idea behind it though so perhaps do some adjustments and bounce back with a second version k.i.u.
Text needs to pop a little bit more IMO with as empty as the right side is. Also, I would like to see some more flow on the right side since it's emptyish you could really make it nice with some blend/smudgework to make it flow a little better. The transitions feel a little bit jagged to me but all in all very nice. I like it a lot, though he looks super scary with that face. Nice job! Good colors and render work!
