jumping free

new koi began in class, a classmate asked me to draw her a koi, she had an accident and injured her hand really badly, so when she asked me to give her a koi as a present...i stopped paying attention to the teacher and began drawing her koi!!!
i love college!

-i would really like any opinion on how to make this one better, or if i should make it look like the other koi, somehow this one doesn't quite convince me...
