Thanks for all the comments guys!
@Isiah: Thanks, I figured with both bionic bits and pelts/teeth/other 'wild' stuff, I'd better keep the colour scheme fairly simple!
@Arkhan: No worries, mate, you're not wrong. Funny how stuff shows up in the pics that you don't notice otherwise, next time I get paints out I'll touch up around the eyes.
As to vehicles, I've got an Ironclad built and undercoated green, plus a Storm Talon in the same state (it's actually a DA Dark Talon/Nephilim as I like the model so much better, but built it with none of the flying cathedral rubbish and just the under wing missiles and nose cannon to represent Skyhammer and TL AssCan).
Next job will be to get the airbrush out to start doing the xenithal(sp?) highlights on both vehicles.
