Kalen Gil- In progress. any suggestions?

I was sick earlier this week. Finally caught up on most of my homework and am able to spend some time in the lab now. I am currently focusing on my bigger character. I fixed a few of the things you guys mentioned last time. he timing and when the arm went through the body. Going to continue to work on this guy but I wondered if you guys had any feedback so far with anything else I should work on.
