Wow, that's pretty nice to see come together...
In terms of design I like the addition of the vents over the engine bay area, but i'm having mixed feelings of the missing sideblade.
Did a quick render on how it would look like with a partial sideblade, I think it would have been difficult, but still cooler and have more a distinctive relation to the coupe.
