I started working on this character during semester holidays, so I had a head start. I took a lot of time to figure out the designs and tried a few new techniques to get more original results. Here are some of the scetches:
These sketches were just a starting point. Once I reached a certain point in the modeling process, I took screenshots of the mesh and painted over it to add more detail.
I had to imply a lot of detail for the insides of the robot, so I built a kitbash library.
Finally, here is a little video of the robot in action. All aspects are done by me.
