[Matra et Alpine]

Looking a good start.
What about approx dimensions tho' ......
Wheelbase ? Cockpit ? Seating position and driver location ??
Can we get a rear and plan view ? difficult to judge what's happening between the wheel "humps".
Engine/transaxle layout ? and sizes ?
The rear deck looks too low for a decent sized engine and intakes. Or the engine looks as if it may sit well forward in the cockpit and needs midget to drive ?
Are you concerned with Aero ? I'd watch out for that flat rear deck - will cause high turbulence breakaway on the rear

oh and rear wheel well - doesn't need to be oval as they don't turn liek the fronts. For drag either close them in completely or to the wheel profile.
