Cutie mark Celestia (without background)

An image of Celestia descending from the sky in a graceful manner. Her cutie mark displayed proudly behind her.
I wanted her to look as if she's going down in a motion of a circular staircase. It may not be exactly that, but something like it at least. I've put the cutie mark in the back later, when I figured it's also circular and she would fit in nicely.

Update: I removed the white background as requested.
