Chroma Circuit Car Variations (2022)

I created these initial car sketches using ProCreate on iPad, to design cars for Chroma Circuit.
The game is a party racer, with the visual style blending between a more realistic sport racer and a kart racer like Mario Kart. The suspension system ingame is exaggerated, so having external wheels is important.
I used Stable Diffusion 1.5's Img2Img to make design variations on them, to explore the possibility space.
