A little, but you aren't taking it far enough. Here's a quick edit.



Notice how you can actually see the shading without having to squint now. I also killed an extra color that you had on his left (the our right) arm.

Also note that shadows are usually more greyish compared to the rest of the colors. You also want to play around with the hue and saturation to get nicer results.

Not the most refined example but it gives you an idea.
