I'm struggling from lack of choices for the options I like. I would love to have a separate Tail Pattern, the ability to choose which ears I want to use, the ability to swap the hairstyles freely, and an option for having highlights in my hair separate from the Fur Color selection. As it stands right now, I absolute adore Face 1, Hairstyle 2 from Face 2, the Ears and EarTufts from Face 4, the back pattern from Pattern 4 and the Tail Pattern from Patterns 1 and 4.
I'm hoping that in the future a lot more of these options become universal on the Hrothgals, since their head-shape seems to be more human-esque and it's easy to see that the ears and hair would all work pretty decently across the different heads by just swiping your mouse across the previews to see them rapidly switch (also because every head already has access to Hairstyle 5, which is the same across all of them and has highlights on it!)
