Battle Mech low poly

Low poly, game ready rigged battle mech. Rigged and animated in blender. Short loop animation is on sketchfab, you can see it on the link provided as well as other details about the model. Concept is mine.

Not bad. But in the present design is something that I usually do not like.
Thin legs. The center of mass is too high. Balance is difficult to keep.
My opinion - the legs should be larger. The design will be more harmonious.
Even human legs compelling cost half the body weight.
