See, I like the desaturation, it looks gritty and really cool, I would've liked to have seen a bit more red on the side panels. I'm guessing there's more gunmetal greyish blue to make it a bit more believable?
I'll admit it was tough making purple look gritty, the yellows and reds didn't help making it believable. Maybe thats why they omitted it out of the E100s.
The E100s looked brilliant, that was a design decision done right! I especially loved the motobugs and buzzbombers because they're so faithful to the original designs.
