The talent is there for sure.
I like a lot of the elements about this. The shading is good, the lighting is good, but the left arm looks really small. Or the right arm looks really big. The rest of the anatomy seems correct, and I am no artist, not by any means, but that left arm is tiny.
Or maybe it's at an odd angle. I cant tell. There is something off about it though. It's the first thing I notice when I look at the image and it keeps drawing my eye back to it.
Other than that, this is a great job.
