Princess Celestia vs. Nightmare Moon

Update 4: I replaced the beams and the ring by colored versions and a sonic rainboom Old version, which one do you like better?

Update 3: I've been told that the wings of Nightmare Moon look like manta ray, so I added more details
I also tried to make her magic look more evil and added shading to Celestias magic.

Update 2: Fixed missing gradients (trees), missing color (blue tree) and floating island, kindly pointed out by ~steeph-k and ~Starsword

Update: Fixed layering error, blurred mane of Nightmare Moon and fixed the color of the stars, kindly pointed out by *ZuTheSkunk

I really want to polish this further, please tell me any error you see.
Pretty, pretty please. This is my first piece with background and I want to improve, but I can't without critique
