Thanks guys. That look from the Grinnell painting - that's what I was going after. I've wanted to skin Beantown Banshee ever since I first saw that painting. AH3's graphics and terrain are amazing - that screen shot is totally untouched except to crop and add motion blur to the background, and a slight blur to the subject.

Sources for this skin were pretty sparse. I had the Grinnell painting, some photos of model kits people had built, and this photo:

That's all I could find. Looking closely at it, I think I need to add some more black background around the name in the noseart.
