Finding a meaning in my art?

You can do that. That would be finding meaning through inspection of Disney related quotes though, so I'm not sure it fits exceptionally well with the theme of finding meaning in your art.

All art is derivative, but what you are doing is basically drawing Disney characters and then taking inspiration in Disney's quotes. Which seems to be a bit too derivative in this case, but creative presentation could potentially make this work more in the arty aspect.

I know you never mentioned how you plan to present this, but here are some suggestions anyhow. xD You could try to draw all the Disney characters differently, overlapping, of differing sizes depending on the importance of their related quotes, and you could be creative with the way you write quotes, skew them etc. If you try to make it more arty in a sense, it would be less derivative looking and more original and more "my art" looking. In this way, your idea could work and I think is perfectly fine.

I feel like this is more out of the norm for an idea for such a prompt though. Usually, the meaning art teachers ask of is achieved through artwork. Words can be a method of expression, but they are not always needed if artwork speaks for itself. And art inherently is all encompassing, but probably no one in your class is going the minimalist route for fear the teacher will mark it bogus or unfinished. xD There are unsaid creative restrictions just the same in a classroom. Unless your teacher is cool with all this stuff, in which case just present it any way you want. I think if your teacher will find you crazy is the last thing you should be considering. xD

Art is crazy anyway. All the toilet bowls and naked ladies and whatever else. This is comparatively tame. Don't you worry.lol
