Well then I daresay you've got them looking spot on. The reason I asked what that they looked so similar, with a few added nuances. You've done a damned fine job with them, then. 
There's an advantage doing it yourself, too: from what I remember, the stock models' UV maps were horrendous.
wish I had my comp back, I'd hand over my tweaked Kessok HP's for Tiq to tweak (I hotrodded my stockers

)
yes, the UV mapping for almost all the stock models is utter crap. Everything was laid on top of itself, and a lot of the panels are individual pieces instead of sheets. apparently the default UV settings in max 3.2 were used. before my windows crashed, I was working at a retex of the stock Marauder. take a look at the mesh, it's not rushed like the others.
I'd have these along with Unknown's versions AND my hotrodded stockers, somehow.
