Real quick response for ya Oboe =)
The screenies you included are actually my biggest panel reference. I tend to cross check with pictures of 38s I have, but the screens you have here are actually where I got a lot of panel lines from. Now that I think about it though, I do think I've missed some, and I wonder if I stopped due to time, and forgot to go back.
In terms of the Panel shading technique you linked to, I use a slightly different method, but I think that when I changed the opacities of the layers, I screwed something up. I'll go back in and look again.
As far as wheels go, believe it or not, mine are not the stock. =) I have to adjust them again anyway to get rid of that white/silver spot I accidently got on them though, so I'll revisit.
Also, check your PMs. =)
