"Frozen" character cookies

Got an order for frozen character movies, and it took me a while to decide against using printable. I found it very hard to get the characters right, especially by piping. So finally I decided I would try it and surprisingly they turn out alright. Since these are my first tries I hope by next order they will get better. Any comments or suggestions are welcome!

I first drew the characters on the piece of paper, then I carved out the characters on cardboard paper. It will be later used As the template.
