Well, don't get me wrong here.. it's a goodlooking model, and there's nothing wrong with high counts, in fact, I'm sure nextgen racer games uses a very high count for their cars as it's afterall the centerpieces of the whole game.
But thing is, as has been mentioned several times before in different posts on this forum. The meaning of nextgen isn't to be able to throw in a lot of pollies here and there so it looks good, and that the count doesn't matter.
Cause the count always matters... Fewer tris = Better performance, obviously
So, what I'm trying to say is:
Instead of just sperading all those pollies out, put them in places where they really matter, and make use of that high count! That way you can get a extremely detailed and nice car, instead of a car having a lot of segments which hardly does any noticable difference.
As I think someone else said though, it might perhaps be better finishing it first, and then optimizing it.. but just so you know.. wasting tris is bad
Cheers!
