Really original idea! There are a lot of possibilities for where you can take this. As I was jumping around, I was thinking of different hazards you could have. Like maybe the main character is like touching up old artworks, having to clean up after bugs or effects of time. Then I thought maybe this paintbrush is a forger and they're jumping around the artwork to learn its design. By the time I finished playing, I thought of Van Gogh giving the player a thumbs-up.
