Your anatomy is broken, the head is too small. Your blue sky would affect his clothing, he has a copy and pasted look because of that.

Meat is correct about your outline, it needs one or none, right now it looks unfinished.

Is the big white circle a light source? If so the lighting it not matching it, put an action figure on a table and shine a flashlight towards it and into your eyes, it would cause a heavy shadow and obscure the figure.

Another issue is that you are dipping into your dark values too much. Do a study with a figure and a flashlight.
