Your shading is a bit nonlinear
Taking into account the "light source", his left arm should be casting some shade onto the left side of his torso.
you could swap the shading on the left hand:
rather than darkening the fingers where they tuck under the the thumb, darken the outside of his fingers along the knuckles.
You can also try darkening limbs further away from the viewer.
For his right leg (our perspective) you could completely shade from his right knee to the rest of his foot.
(also agree with what SchAlt said about shoulder pads)
I'm just cherry picking smaller things here, I hope I'm not being too vague, your digital art definitely carries over from your pixel art, and it can be a little weird switching between the two.
