It's always hard to study when you have a little dragon pet messing around with your set up.
This was a drawing challenge I had done between me and my sister were we tossed each other 5 images to reference off of and make a picture from. Mine was a an interesting mix of witchy-related stuff and the first thing that came to mind was a witch having a study session.

This was done with pens and Copic markers with a tiny bit of white gouache and colored pencils.
