Playing Dress-up

So my girl and I had a day in the house today, and she wanted to do make up and dress up as Elsa, so I thought I would take advantage and take some photos (obviously!)  I managed to source a frozen-ish digital backdrop and made up a wee composite for her.  I must say the background looks better than my living room wall paper lol! I am still very much a novice at this and still have much to learn, but I really do love doing different things like this.  If anyone has any hints or tips they would be gratefully received :)
