Neo Racer Track Designs

I did some rough sketches of different track designs using other tracks from the Cars films but also games like Mario Kart for reference. 

Development- These are the designs I liked the best, so redrew them out larger and neater to see if they would work and if I thought they could work enough to be the finished track design.

The last one is the one I chose to use for my final design. I think it fits the tital "Neo Racer" best as I can imagine the loops being lit up neon colours and it looks the most modern.
