One of the coolest things of making SD figure (Super Deformed) robots is that I can manage the proportions as I want, this figure is an example.
Having the MP01 model before,( I will upload the modeling of it too) I make some adjustments for the new figure. then a few color test and finally, print it as a keychain.
Testing materials with a bit of patience using procedural rextures.
