I sketch cars non-stop.^
I started about three years ago. Began with getting my lines down. Worked on perspective. And only until somewhat recently have I gotten lighting somewhat down (I never knew how important lighting is).

Hold out for the BRZ STI or... Rocket Bunny FRS. Update: Scratch that. I've got a 2015 5.0/6MT with my name on it.
