Very nice! Some constructive crits:
1. Like ransick said, it looks like it's floating above the ground plane
2. The seats look a little...stiff...too CG...perhaps it's the material or the harder edges...maybe a smoother chamfer over a wider area could help. They look a little small also but maybe that's how they are in real life?
Keep up the good work!
