Here is a lovely Lancia Stratos HF, doing it's thing. The decals really make this thing badass. Probably my favorite car design ever.
The process for this study was to trace over the image with paths in photoshop, have the main colors broken down into big blocks on separate layers, then use the preserve transparency option to keep my painting within those blocks. Block in main values/reflections, then move onto details like headlamps, decals etc. And about 4 hours later, Stratos!
