Originally, my group wanted the girl to be painting a comet through the sky. We quickly realized that this would be more difficult than we thought, so we changed our idea slightly. The girl ended up brushing her paint brush over the stars.
If I had done this project on my own, I would have probably rotated the background so that it was horizontal. I probably would not have added the comet, because I don't think it looks like it belongs. I would have added more stars in its place.
