That is a very cool mane with the braids and I like the glow you're getting from the light. The overall comp is a bit bland IMO however. Those braids may have been a good item for a closeup study perhaps? Just thinking out loud. Good luck.
I'm no expert, but I think you've done well with the exposure on the mane, giving it an ethereal feel especially at the ends and the whispy loose hairs alon the neck.
