Teens Tails and Christina

I really like this drawing, it's very cute. But I don't like the color of Tails' hat. Sadly, I forgot to bring a red color pencil to school that day. Originallly Christina was gonna have her head on his chest or shoulder, but I kept messing up, so instead, it ended up like this. But it's still pretty cute, my classmates think so. So you know, the building is supposed to be white, most of the buildings that sell stuff over here where I live is white, so nyeh. Christina belongs to me, no stealy, comment please. You know, it's been a pretty long time I've actually have drawn Tails or Tails with Christina...
