At my high school, the seniors got to paint a small picture on the wall before they graduated. This painting is mine- done with acrylic paints. The tree is the division between day and night, and there are two ice phoenixes, one on the day side and one on the night side.
NOTE: the black background around my piece is because other people had painted their own pictures all around my own image (my camera wasn't able to crop out the others' paintings).
