Aw man I had a big reply but then I clicked the image to see the full thing and it took me to imgur and I lost it
Summary:
Looks like album cover, squareish aspect ratio and place for text, though thinking about it that's where the comic title would go. Character ok, not revolutionary but got interesting bits like the nose style.
If you don't mind starting again try a different camera angle, anything that isn't straight-on mugshot. Either way, would recommend bumping contrast hugely to give a dramatic silhouette and accentuate whiteness. Look up some reference for the horns.
There I think I hit everything, and it didn't even take long.
