Sonic Riders Zero Gravity Sis'

Honeslty.I think I did good. But you can see where I earsed it on her head. The purple girl is me of coarse. The person in back is my sis. I drew the person in front and my sis did the back. They are obviously racing together. I got the idea from my game Sonic Riders Zero Gravity. And me and my sis LOVE it. So I did this in memory of it. HEHE. Tell me what you think. critique me if you wish. I REALLY wanna know what you guys think. My character name is Super Nova. My sis' is Metallic Rose. ( Super Nova's bio ) She LOVES RACING. Most of the time she hangs out with Sonic and his friends and helps in there missions. She races by herself mostly because her friends are always busy. She often get lost in her board. In other words, she loves to races ALL the time. She also forgets the time and ends up racing till night time. She ALWAYS get lectured by her sis because she was out so late. Please tell me what you think. I also kinda took Sonic's pose off the front cover. HOPE YOU LIKE!!!!
