It's the Great Pumpkin, Autarch Brown!

I highlighted and shaded one of the Scorpions to completion this week to start to figure out how I'm going to paint these colors. I'm pretty happy with the blue-ish grey weapons and the canopy/gems but I'm not quite there on the orange and black. The orange was highlighting with Troll Slayer and Lugganath, I think I want to try those again though as the highlights aren't stark enough for me. Thoughts? Same for the black, that was Eshin Grey followed by Dawnstone.

The one panel I left orange is for a transfer I hope to print out. I finish it up once I lay that down.

Any other thoughts on improving the colors or adding accents?
