It's a lovely dream (come true, I hope!) filled with wonder and excitement. Twilight Sparkle shines with joy as the Night Goddess and all the elements of the sky glitter and shine, dancing and swirling all around her. The stretched and wavy look of Luna's wings give it a much more fluid feeling, more like she's swimming in the sky. She looks so clam and even a little adoring of the little pony, and I like how they both have their forelegs raised (relatively) in a more exited friendly greeting. The color and contrast make everything shine, and it's all very sweet and imaginative.
