Good colors, blending, flow, lighting, the grainy texture on both sides kills it for me though.

I actually hate the colors, think it's way too montone and makes the piece look flat.

It's a bit flat and too dark. I see a weird outline around the render too which makes him look weird, the right side is great but as kotora said the grainy texture doesnt look all that good. good flow tho and I like where you put the light source :-)
