This was one of the 11 tarot card designs I was working on over a course of 5 days. This was done after Celestia, and took roughly 3 hours from sketch to finish. I originally tried to get Luna's wings blend into and morph with the clouds, to give the appearance of her being a part of the night but it didn't turn out how I pictured in my mind. Also I wanted to have the mane appear as a negative space, showing a portal like image of deep space, though that looked odd so I changed it. This Luna is the Moon card in the MLP Tarot deck.
Even if I hate MLP so much... this art looks beautiful! Or even more than beautiful!
This is exactly why do I love MLP so much
Keewl! And I can see where you tried to blend the wings in with the clouds. It's still a nice effect
