Sketch of the Week: Cactus

Today's sketch was inspired by a cactus that lives outside my apartment. It's been growing there for who know how long, but I've always enjoyed watching it change through the seasons. This drawing was done in February, before its flowering season.

I liked the cactus for its simple, elliptical forms. I thought it'd make for a nice color aquatint, if I ever get that equipment at my disposal again.
