congratulations on this effort. very impressive for the first attempt.
a few suggestions i have are, the rear wing shape is too shallow and needs to be deeper in HD. bare in mind also in 2001 the regulations restricted the number of elements allowed. I think it was 2 for the whole assembly. so adding another element in HD would have been illegal. I could be wrong but check it out.
It's fun to drive, but from the onboard footage ive seen the car always seems to be a bit pointy. the rear is stepping out but is easily correctable.
I look forward very much to your future work.
