Flatspeed Racing Sweatshirt

Spent the past few days sketching out sweatshirt designs. My brother's looking to make some clothes for his Flatspeed Racing club so he gave me the logo to look at. I had some fun trying to incorporate it with some other ideas I've had lately. I like the idea of taking familiar, ubiquitous, boring clothing like sweatshirts and adding new, subtle twists. Here's the results, including preliminary sketches and design notes. Click on the images to see details up close.
