In the first piece, for singularity, I chose to center the composition around the most readily apparent aspect of sweet gumballs: their spikiness. I used triangles to roughly convey the points of a single gumball. Using triangles rather than the ready-made "star" resulted in a less even, measured look, which is successful because it seems both more natural (evoking nature, the prompt) and more "jagged" (evoking sharpness, like spikiness). I think the composition overall works because literally every visual element is a pointy, straight-lined triangle, making it overall very singular yet still recognizable as a gumball.
