In preparation for the Caves and Cliffs update, here's a (mining) robot made out of copper! The green bits are supposed to look like gems or lights, but their colors were taken from oxidized copper.

All colors were sampled from the various copper blocks, and all pixels were placed by hand (no copy-pasting). It took me an entire weekend to come up with a good design and to get the texture just right on all the surfaces, and I'm really happy with how it turned out. I hope you like it too!
