It looks pretty good. The design of the new car is interesting.
I hope you'll find some people to help you in the design of new circuit and to improve the whole game to make a true Super Cars 3. The idea of mixing Super Cars 1 & 2 is nice and finding pixel graphist artist is a bit hard nowadays ?
As there's some people from the Amiga Demo scene that come sometimes on EAB i hope they could give the link and so find the support you need.
Anyway good luck, may the schwartz be with you !
