The joints could be potentially overpressured or jammed by shells, so you should add some sort of joint shield. (though it might limit flexibility in certain directions) Most of the turrets seems to be flak or AA. It's the early 2000s, buddy. Have some radar and missiles instead. Also, have a few cameras or sights to see better. And also, hydraulics can also be overpressured. The main frontal turret doesn't seem to have much horizontal traverse. The guns could also be longer. (distance+speed)
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.
