Okay! I tried to fix it -er kind of.

Nice rendering, reminds me of the works of Delicious.

The only thing really bothering me is his right leg (on the left side for us). I think it should be a bit more in shadows, I'd try swapping the colours there for at least one tone darker.

 I agree! I will try my best to fix it!

Who needs full on evolution when you're that ripped?

Your colouring and shading have definitely improved :)

One thing that bothers me a bit is the length of the legs: his right leg (left for the viewer) seems to have no ankle like the left one has, making it quite stubby.

I think it's a lil bit over-detailed which makes it look like a mess to me. Another reason could be that, the darkest blue and the outline color have very close luminosity.

It looks very nice at 2x Zoom.

And i can practice subtle dithering by observing your works. Shading is nice too, but i miss arms so much =)
