i can't get it right, i would like someone to add color, i'm not very good when it comes to anime color!

ok, i'm not happy at all with the outcome. what happened was is that i started this drawing befor i had ANY experience drawing on this site. now that i have a little bit of knowledge of what's what, i already have a half way messed up drawing. it wouldnt've turned out even this well if rosalyn and kenshin didn't help. thank you guys!
