You missed some spots to the left focal point out there. And you're loosing your audience by having that huge hole of brightness up to the left cause the eye tend to go away from that spot cause the brightest thing is generally what eye tend to look the most. You need to choose what you want to show to your viewer and catch his eyes in that spot, it's a basic rule but not always known or said

His Hand is too blurry(fingers) and its maybe also slightly oversized but I am not entirely certain so need 2nd opinon on that.
it seems almost as though you spent more time on polishing and smoothing the cloths than the actual figure because they don't have any of thes rough strokes.

Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so."
