This is a 3D sketch I've done today. Took me 1/2 hours.
I wanted to create some kind of mecha that wasn't build for war but could act as a support/repair mecha in war.
Unfortunately it's not polished nor refined, lack of time won't let me do more on this piece.
My next piece will be more elaborated and will be Star Wars related.
Models were done in C4D & Zbrush, then a white render is created.
The rest is painted on PS with my color picks.
Apps used: Zbrush, C4D and PS.
