For some time I've pondered how to incorporate Para-Vipers into my classic-centric Cobra display and I think this is the answer. You've really made yours nice and cohesive, I think they would look great between my Siegies and Stratovipers. I'm wondering now whether it would be worth the extra effort to paint the jumpsuits grey. It's perfect as you have it but I'm slowly coming around to small details in sharp contrast - like you have the goggles in that haunting shade of green which still looks sensible but pops against the red... and I think a grey for the suit would fit the bill for my version if I make one.... something like...
But I love the goggles on yours so I go for that,,, the suit should be less blue on my mockup too, or maybe not. I was thinking something like a field grey. I also did a mockup of one in Lampreys colors which looked surprisingly alright.
