I don't think you failed. Her face expresses deep feelings, and the way you texturized this artwork gives to it such a surreal feeling that evolves the viewers and contrasts the character even more. Her eyes attract our attention... This artwork is very special and stunning.
i think i have problems with human drawing, portraits especially actually it was my first watercolor portrait ever so i can't believe that girl even looks like a girl, i guess there are a lot of mistakes. but i will try to do my best. thank you a lot, i'm really very happy you liked it^^
