Worked on this for two days, and I'm really pleased with it! I know the proportions are off in places, but I'm learning and improving with each new drawing. I drew this as a gift to someone who knows who they are.
Update: I spent another day adding a blackboard covered in mathematics, requested by the person I gifted this to.
Update 2: I just came back to this drawing and added shading and a bit of lighting and stuff.
