She must love the results! Fantastic storage in the cubbies and a princess sized closet, you got it all in there. The loft will be a space for sleepovers? Some people think it's crazy to design for such a short time in a kids life but I think it's well worth it. You can redesign it if she outgrows it.
I built our daughters bed into a dormer space(the larger mattress is crammed in) which makes it just a bit short for anyone over 6' tall. Even though she only comes to visit from NYC these days, she still likes that room the way it is.
