Well the shape is similar to other cars because of layout and ergonomics, how else do you make a car with passengers, visibility, and a huge engine sitting behind? There's not much you can change...good thing everyone thinks the cars you listed look good
I'd be up for a steeper rear window and slightly less "sharp" edges than the original NSX, which is what the concept looks like it has. The front isn't particularly attractive though :/ Are headlights that low even legal? They don't look good so they better not be lol. And the Acura beak needs to go :/
