Even if the pictures girlie, it's still workable. I always loved Luna's color combos XD. Amazing job on the painting details. You really make her stand out considering the sparklie star background is there
OMG! I know this is totally unrelated but... see, I have these pajamas and they have kitty images on them and it says Kitty in the Sky with Diamonds and when I saw your title it reminded me of my pajamas! Anyway, it's a really great drawing, I love the use of colors and Luna is my favorite pony.
