Ahhh this is really nice, I really like the finished version I don't know why you are not satisfied with it, well obviously as an artist I understand that we can be a harsh critics to our own art, but you should feel good about this one because ... it is good! XD XD          
         
I like the rainbow colour palette that you use on this artworks :).
