new room decor

It's no secert were moving to Tennnessee in a couple years. So I've been designing my new bedroom in my head. First it was a Venetian theme like it is now, then nature theme, then a music theme and that's become rocker chick with a country twist. I've been looking at decorations on the internert, I'm so confused. Do I go Venetian, go with my nature idea, or stick with my rocker chick with a country twist decor? But I do have a couple years.
