I think the legs should be larger or more armored. (important for support, if one or two legs go down the whole thing will fall, also the cables seem to be a weakspot) You should probably add a few internal missile silos to launch anti-mech missiles or cruise missiles, and maybe add a CWIS, since the large size of the mech makes it a target for planes. Also, maybe add a gun at the very bottom of the thing since the underside seems unprotected. Add some mortars/artillery too.
