I love this piece love what you did with this the darkness and the "EYES" I do think you should have added more glare and shine to the eyes but you have some nice work here very well designed and created. great shades and depth all the way around, This style was pretty interesting, it could be better with a few more details and effort, just take your time and keep at it, and dont take light to the improvment points suggested. because they will help of course and bring some better resluts all around.

more glare and glow on the eyes would be nice but maybe not your direction.
