Thats a VERY bright shade of green... I think a little too much for an Imperial force. Its bordering on Striking Scorpion territory.
Sorry for the late reply. It's been ages since I could get anything 40k modeling wise done.
Anyway yeah, you're right. That is way too bright and Eldar looking for Imperial forces. Since then I've pretty much settled on making them a force of the Jakals so it's not a problem.
And here's my latest efforts; another Valkyrie almost made:
Right now it's in those sections for ease of painting, but they can be popped together in the unlikely event of a casual game happening. All it needs before that is for the weapons to be magnetized and attached, the canopy and door gunners to be attached, and then to be painted. So...still a lot to do.
There was also an unfortunate cock up with the hinges of the rear boarding ramp which has forced me to glue it shut in order to keep it attached to the model. I'm pretty annoyed at that. I've been making a lot of mistakes modeling wise with this project!
