You guys need to do Normal mapping and bump mapping on that to cut down on the load times with models like that.
The polygon count on that is probably astronomical. And seeing as how a lot of people here don't have that great of a system (some of you do, not talking about you guys) It would probably be a wise idea to have a stunted version of those highpoly models for the low end systems.
Like using LODs (Level of Detail) or something to that effect.
Have a Light version for the SH3 style rigs (None of the grid work on the hull, it's all in the textures) so you don't leave those guys with crappy framerates.
Just my two cents. Looks great anyways
