Wow, awesome experience, that you told us! To see a fullmoon rising... it must have felt so epic and emotional. I'm always so happy to read about that kind of experiences ^^ And I bet it is that experience that inspired you to make this Luna PIRL! Which is a great one... I can't believe this was originally a day picture, it looks like it was a night picture from the start! Which means you did a great job!

I also love how Luna's mane and tail are designed with the FX elements. Only (minor) thing, upon a closer look it seems that the mane and tail share the same layer for FX, while it might have been slightly better if they had separate layers. But that's being overly critical really, this work is awesome ^^
