Sonic Mandala - Art Final

This was my senior art final in my art class last year. The project was to draw an 8-circled mandala and fill it with pictures and things that describe yourself. I decided to draw one thing, and of course that was Sonic. This took a bit of planning, but I just love how this turned out. I put the 7 Chaos Emeralds (green one in the ring behind Sonic), The trademark ring and banner, along with Sonic of course. I hope everyone likes this drawing, please comment :3
