Half-and-Half Drawing

This is the drawing I did for art- the one where you had half of a picture, and you had to draw the other half. At first, I thought this was going to be easy. But I was proven wrong. Talk about complicated! All my friends around me had great work, while my colors clashed. My parents thought it was "excellent" and "wonderful" and "great" while I thought it was a piece of "junk." I didn't think it was too great, but it also wasn't too bad.
