To be more precise, a slightly blurry, low-quality picture of a study of a towel that's crumpled at the top and then sort of drapes down.
I drew it in about 40 minutes.

(edit: will upload higher quality picture in a bit)
another edit: I posted this super fast so chibibo could see before he had to leave. More details: Done with 2 Prismacolor soft core colored pencils, one black and one white, on beigeish grey textured paper. It was part of a class I took on black and white on colored paper.
