Here's a painting in a day.
Jimi Hendrix. I'm not really a huge fan of Jimi's material (something that seems to be a running theme with my sketches) although I really like the album Axis:Bold as Love. I grabbed some gouache and some black ink and started messing around with a piece of masonite board to see what I could get. So I guess this would be like a painting sketch. On a side note, I always thought it would be interesting to illustrate the lyrics to Spanish Castle Magic.
