I love the idea! It looks super nice and fun to play! :)

Oh I love the topology here!! The 3D effect! And the colours are really well used as well. 

Awesome job! The game makes me think of Kirby’s dream course! You should definitely try to turn this into a game.

Really great work, I love the terrain! 

that 3d effect on the landscape is quite nice,I think you have a pretty good use of the blue color throughout the piece, good job
