I never even thought of making the grenade launcher barrel silver.
is that an actual fade on the shield, or just the lighting with your red/orange metallic?
2 1/2 weeks you gotta be kidding mine took six months what are you a MACHINE? 
What'd you use for the head vulcan barrels? Just curious.
The fade on the shield is an actual fade from straight clear orange, to the red/orange mix I used for the rest of the kit. I wanted to break the shield up a bit, and try and seperate it from the rest of the mobile suit. There's SO much red that I figured this would be a cool way to bring the shield out from the rest of the kit.
The thrusters are a bit oversaturated with the blue, but in person you can see the gradient from the blue to the bare aluminum alot better. But I agree, I think the blue could have been toned down a bit.
Thanks for the comments guys!
