To be honest, the idea of a "Dragonesque" Celestia flying around the Eagle Nebula is sublime and majestic, and also, I think it's a beautiful painting. If it didn't go the way you intended, it's ok, you can use this one as a sketch and study a little further the elements of it in order to bring the real painting that you envision.

But nevertheless, it's still a wonderful job, keep it up!
