hehe, I'm fine with biased reply's. Design aesthetics tends to come down to personal taste, so everyone's opinion is different, but at least then I can get some feedback on the Design itself.
I like the muscly defined upper arms. and I like the forarm and thigh plates matching, keep that theme. I think I like the 3rd missle pod set best. maybe put some reactive armor on the shoulders? I'm not sure what else to say that isn't biased, since I'm making a similar mech as well...and every idea I was about to suggest…
