Prototype LSX921 is the concept car I modeled in Autodesk Maya a few years ago. The inspirational car was a McLaren GT3. I did my spin on that and made a new concept car. I didn't do any sketching and 3d concepted it on the fly when modeling, I had several ideas on how it should look and had a lot of different references on different parts I found interesting. I'm currently doing more renderings in Cycles, testing a little on how a livery design could look on this concept car. It's a work in progress and I will update further with renderings. I'll continue texture paint in Blender and see how this develops.
