A semi-rough pencil sketch of the automobile owned by Leila Martin, a female wolverine from the bounty-hunter group "Caterwaul". It's old-fashioned, low-tech, and pretty rough around the edges.
No rulers or references were used. Looks like a mixture of some Chevy, Mopar and maybe a little Ford thrown in for good measure. I haven't drawn anything in many months, so I thought this would be a good "warm-up" to get back into wielding the pens again.
Approximate time to complete (from blank sheet to finished sketch): 2 hours. Yeah, it's slow. Like I said, I haven't drawn since earlier this year.
