the one on the left is a based on a super old drawing of her I did in my teens, it's somewhere in this gallery if you can find it that is.
middle one is classic moondancer with some tweaks, such as stylizing her side bangs, but this one doesn't deviate much from the original.
whilst the one on the right is a more 'adult' take on her manestyle, I wanted it to look more relaxed. So I brought her ponytail lower and shorten her cut.
let me know which on you think suits her best! I personally don't have a strong preference towards any, they all honestly look like moondancer on different days.
