April and her art
She doesn't need a fancy art program to validate herself as an artist. She can just sell her work in her shop. It matches the kind of merchandise she sells, so people who go into her store would naturally be drawn to her style. Plus she would be able to profit from it instead of becoming a "starving artist"...
I don't know why she feels the need to give up art...
