A few perspectives seem to be a bit off, but overall I actually love it!
The design is awesome, and yeh - it does look seriously cool!
Only thing I might be slightly critical of is the structural rigidity of that roof structure should the car roll. However I'm assuming that it's not 100% glass right around the rear? And that there is a 'blacked out' area at the corners concealing a support pillar? (just under the two yellow fins at the rear.
But yeh - really nice work, and I'm liking the rendering style! Keep it up
