Added black, gunmetal, a bit of red, a bit of white, and then some clear blue and clear red over silver for the lights on the grille.
Neat! I'm surprised you didn't add more detail to the lightbar on top though. You know, red on one side, silver in the middle, blue on the other side?
I like the added coloring, but I think the panel-lining is a bit jarring. I think a cold gray would have suited it a bit better.
I thought about going with gray instead of black, but it felt like it might be too subtle since the rest of him is just white and black.
