IT AIN'T OVER 'TIL IT'S OVER!
Klee Shay was created as a reaction to trends in character designs I was seeing at the time, so it's only natural that she'd evolve to keep up with those trends. That said, I don't know what I was thinking making her teal at first. The Disney-style-animal-drawing crowd that originally inspired the idea doesn't make much noise these days, so I haven't had any real call to draw her in this form, or any new trends to adapt to, so all the recent changes have been backported from her other forms.
Some further adjustments might be needed. I'm not fond of how much purple there is now.
EDIT 6/19: Adjustments have now been made. I think this works nicely.
