There were numerous problems with Day 1, which ultimately culminated in making Ehrlynn's visual introduction less attractive than I envisioned. The most notable difference in the redesign is her hair color. Originally it looks gray colored, some would say "wig like" and they wouldn't be incorrect. The silver/platinum color didn't translate as I intended once under more realistic room lighting.
My initial test on Ehrlynn's new hair coloring drops the silver entirely. I think I've fairly well established her main colors are purple, green, and pink. I haven't yet fully decided if I will darken her hair color further like the eyebrows and eyelashes.
Another test shot. Note that her wings, tail, hooves, and horns remain unchanged. If it looks different to you then it is only because of the better lighting.
Overall, I think the succubus form rework is a better fit for Ehrlynn's dual roles of soft and hard. As always, I want players to be pulled in by the visuals and I believe the rework better accomplishes that objective.
