It's a good system, but I really think the style they're made in is suited for Kindergarteners :S.
Maybe you should look through a few art sites and imitate a style that seems fairly popular (a fairly good dressup is one from Gen8Hedgehog on deviantart).
Also, spend more time on the pieces. In the face option, the faces are disproportioned and not even symmetrical.
So... yeah. Change the style and work harder ^_^.
