Hi,
I just finished repainting my Exgraver, it still needs some touchups here and there, but I am happy with it. At first I was going to weather it and make it look like a real digger, but instead decided to go for a cartoony look that complemented the cartoony design. This figure is really fun, and I cannot wait to see the completed behemoth that will be Hercules.
I plan on mounting two of each of the black guns on the outside of the forearms to cover the coloured treads in combined mode. Not a huge concern with the dark purple of Scavenger, but Bonecrusher's green may need some hiding when that comes out, lol.
