This has to be one of the best, sweetest beauty portraits I've seen of the Princess of the Night. I love the magical "fog" that her mane surrounds her with so that, along with the crescent and halo of darkness, our brains don't think twice about not seeing where the rest of her body is. (It's like she's sticking her head out a windows). Her face is especially pretty, and I love the extra stylization on her livery collar (or breastplate or even necklace to some, but I prefer the quite apt double entendre). For some reason (the face? the moon and sparkles and "smoky" parts) she really makes me think of Bewitched. Eyes are much prettier though, and she's too cute for any annoying mother to come bother.
Now, the only thing that stands out is some brush stutter (grays between the smoky and the mane), mainly on the left-most and right-most areas where the outside of her mane meets the moon.
Anyway, lovely work you can be proud of. Thanks for sharing.
