The character I'm working on (pictured below) has her roots in being based on the design - but not completely; I've got enough originality to have made the tweaks that I wanted in order to make a unique design - of a minor Phineas and Ferb character with a great hairstyle, but there's a bit of a dilemma in that she's never shown facing the camera, so I have no idea what her hairstyle would look like in that style, and perspective-wise, I can't picture it or try to reverse-engineer it in Moho.

The lefthand face was the original attempt I made last year at designing a new character based on the general likeness of a preexisting one. It was largely traced, but I made a couple of changes to things like the nose and ear, and adding a bun to the back hair layer, to make it a bit more original. The righthand face is one that I'm drawing from scratch, still in a similar style and likeness, but with the goal being to start with a frontal view and have a smart bone dial that can make the character's hair consistently resemble the hairstyle on the left regardless of if the character is facing to the left or to the right.
As I said earlier, I've had this problem with a multitude of different character hair styles, when it comes to preserving a 3D sort of illusion to it, and I could really use some help in figuring out how to go about making smart bone dial head turns with somewhat complex hair styles. If anybody could give me some advice/instructions on how one could go about mirroring that sort of thing (that is, more advanced hairstyles), I would greatly appreciate it.
