I came across the contest for this and I thought it was such a simple idea that I dove right into it. Turns out it wasn't very easy, flowers can be difficult to design.
The way I went with my design here is I wanted it to be "box like" so I drew out a square and symmetrical looking flower. I also wanted it to be unique and have some character to it so instead of making the flower look like an icon, I drew the flower by hand and it gives it a more personal feel.
