The vehicles are depicted above are recreational sports vehicles, sort like jet ski in the air. I imagine them bering rented out at outdoorsy places. People who are more adventurous will take the green vehicle(2kn) while people who wants an easy ride will take the red one (Kestrel). As far as the artistic style is concerned, I wanted to create sort of retro-futuristic/Disneyland poster look. The main ideas I wanted to convey were fun and excitement.
The vehicle was created in maya then rendered in photoshop. Below are shots from various angles:
Below is the 1st pass at the vehicle:
