Prismacolor pencils on toned grey sketchbook paper. Not too happy with the wings but overall satisfied. I don't very often work with colored pencils let alone do fanart. I wasn't able to satisfactorily make the crystals growing out of his tentacles look that crystalline but the sketchbook is only 5.5 x 8.5 anyway. Not a lot of room for squeezing in fine detail.

I always loved and was confused by his big tentacle feets.
