It’s definitely a cool image!
I’m not sure it meets the brief though - assuming I’ve interpreted it correctly. 
The key point for me is ‘design a vehicle’ which implies creating something from imagination rather than illustrating a real car.
There’s no reason you can’t reference real cars for inspiration though (a concept artist usually would). I once used a vintage racing car as the basis for a racing droid design for a contest (think it might have been a Shelby Cobra! 
).
Anyway - I didn’t set the theme so better ask @Katamaheen for the correct interpretation!
