That's looking good, Rokket - and don't just consider the limits of your computer,  also consider what the "system resource" load on the end user's computer will be.  I think it would be best to just get the main features and leave the intricate detail behind (maybe add some detailing with displacement mapping), so even folks with modest older computers will be able to enjoy actually using the finished model.  I refer to this (borrowing from an old preacher, J. Vernon McGee), as "putting the cookies on the lowest shelf, so that even the smallest children can get at them".

     It remains to be seen whether my contribution will look acceptable, but I think  an EZ-posed flame trail (to fit road curves) and an EZ-posed flaming chain/whip are doable.

     An animated refractive flame ghost version of Roxie (ultimate "hot" biker chick) should also be feasible;  but I'll want to generate a seamlessly looping (tiled in both space and time) flame texture.
