Recently did this for a competition at 3d Concept Art

I used Moi for prototyping the weapon shapes and various robot bits then retopologised. The rest done in Blender unwrapping posing e.t.c.

I'm glad the normals now work properly.

Rendered in Thea Render. a few bits in Blackmagic Fusion (sparks) and a little Photoline to finish.
