Conceptual Limitation

This is another piece of fan art that I did for the only fanfiction I really like: Harry Potter and the Methods of Rationality.

This is about chapter 28 when Harry transfigures only a piece of an eraser, but forgets some important rules.

Like watercolor, marker is not my medium. I'll have to keep looking.

The table is not described in the story so I decided it was covered with a white table cloth.

Comments and criticism welcomed, if I know what I've done well and what I've done horribly, then I can do better next time.

Also credit must go to my older brother for finding me the time independent Schrödinger equation with arbitrary dimension. Also for teaching me that phrase.
