Fixed it a lot. I'm thinking about adding infected stuff to the chest also.

shape of the delts are nicer, I like the skintones alittle more. Clavicles are heavily messed up tho, imagin clavicles like this this shape ~ that would be on the right or from his pov his left clavicle.
pecs n abs need some fixin
.
Nice mecha armtho, really diggin that.

Reminds me of the dude in District 9.

I dig the infected part.

oh damn I knew I forgot something
