Character Silhouettes

For an assignment, I was to design 6 character's silhouettes. I needed to have each character inspired by a shape, two for circle, two for square, and two for triangle. Then, I was supposed to choose the two strongest silhouettes and line the character. I got some feedback on which was the strongest, and most people said 1 and 5, so I lined those characters. I would like to line all of them eventually!
