Here's what i meant with the feet. Yours look like the right.Not quite THAT thin, but i'm just emphasising the difference. They should be taller for how long they are.
I think for the arm you should either put as much detail into it as the tank itself, or scrap it.
Coz a single jointed arm made of large blocks and cylinders just doesn't fit. Given it's size, it would just be a metal frame with hydraulics and cables inside. Especially if the workshops meant to be built from scrap in some rebel hideout, they likely wouldn't be adding unnecessary parts.

That's what i meant by smoothing. Second heading down, "Smoothing parts of a mesh"
