[@Crusader Lord] That is...a tad powerful. The general rule is don't go Madoka level or beyond. Perhaps take out the "unable to fall" part? Then you'd have a pretty damn powerful girl *and* she'd have a potential neato star theme. You'd probably have some manner of raw energy manipulation/special theme. References to stars and not falling, combined with your character's general poetic, grandiose nature would point to something like that~

If you want help fleshing this out I can PM you whenever!
