Brawl was basically repainted with Testors Dark green drybrushing, then added slime green highlights to his robot body to make it stand apart from the vehicle shell. Basic blackline and details were added with Gunship Grey and Hobgoblin Grey stripes on the tank body. A light drybrush of the grey was used on his black parts to make the detail stand out and I'll probably do this from now on. Enjoy!
Need a fix for Brawl's floppy shoulders? The tab/hole that connect his shoulders to his body need to have grooves filed on them so they snap together. Take your dremel and carve them as shown in the pic below.
