I prefer the two eyes, but they look like they are stuck on as an afterthought. What if they were elliptical (major axis being horizontal) and set back into the head a bit further? Beneath and behind the eyebrow instead of being in front of it.

I'm not sold on the 'muscles'. I think you still need to see part of the frame beneath.

If I remember rightly, MegaMan had oversized feet which a lot of these anime style robots do.
