In real life industrial machinery the thing gets thicker the lower you go. Especially in an "unflattering" way. Like this mech is human shaped. If it were a human male, broad shoulders and narrow hips would be ideal but a machine built like that would break. Every component would need to be built to lift every component on top of it.
Pic related is a real industrial robot. It tapers. It doesn't look like a sexy human arm. It looks dumpy because it get wider as you get near the base.
