Looks good dude. I like the shine on the hair. The bottom half of his hair is really boring in comparison. Shading for the most part is good, but theres some boring/pillowy areas like the shoulders and wrist guards. Good work overall.
I think the outfit looks really good, I can't see the little details from my phone but it looks solid (no pun intended). The hair looks good but the shading clashes a bit with the face. I would also recommend defining the nose a little more and making it thinner. Raiden has a dainty anime-ish nose, the micro has a pretty broad nose.
