The feet and leg design looks good, I rarely see anything like that; it certainly gives the mech some of it's own character. Another thing I like is the armor around the cockpit. The plates covering the shoulders, as well as the frame you built around the windshield gives the mech a heavy, utilitarian feel. Reminds me of an armored fist. The only complaint I have is the coloring. I think that you have a bit too many colors mixed in.
