It looks super good. You have a seriously awesome command of pixels. There are however a few things i cant quite put my finger on that degrade the quality of your work though. The drawing seems pretty 2d but mixed with the awesome shading it feels kinda weird. The lines of the dawring are kinda weak (ex: Shoe) Also there are some lighting issues that i see (im potentially wrong though so ignore if the need be) Since his left arm is dark cuz its in the shadow of his body why is his hand in the light? With his eyes shaded in above, be it cuz of his brow, it looks kinda odd when generally the eyes would be very reflective cuz theyre wet. I also find that the transition from your brightest colour to the second brightest (first layer of shadow) isnt contrasting enough. When you zoom out you can see this problem especially well. The dark red/purple is either too dark or the first darker yellow/orange isnt nearly dark enough.
Just zoom out youll see what i mean.
Other than that it looks great
