Help me find things to decorate my "Starry Starry Night" room?

Okay, since we’ve just moved, I have a brand new bedroom! I got this big poster of Van Gogh’s ‘Starry Starry Night’, and I’m looking for decorations so that I could have a sort of theme.

I’ve been searching on Etsy for star themed objects, but they mostly have jewelry. Does anyone have any Etsy-like websites, bedroom ideas, etc?
