In this update, I changed the material for the silver metal, as well as adding more minor details around his joints. I played around with the screen on his chess but was not completely happy with the result as it doesn't really seems to fit with the overall character's look. I also wanted to add some more details to him but by doing so, it makes the character look a bit distracting.

After seeing and getting a chance to texture this awesome robot, the first thing that comes to my mind is to put him into one of my all-time favorite movies universe, WALL-E. Initially, I wanted to texture him the same color as Wall-E, however, since the concept already used that color palette, I decided to switch to a different color while still keeping the old/rusty look, and red was one that I found that suit him best.
To conclude day 1, I think that I have a solid base to work on. The next step I planned is to break up the color a little bit more, as well as giving more details to it.
