Alright so here's some stuff I think would be pretty cool, regarding the mane customization.
1. Fix the fluffy mane, the fluffy mane is mostly used in videos I've seen to portray a noob, and i think it could have a revamp? maybe even fix the shading on it too.
2. More manes, as for the felines, young adult lion manes would be cool. Oh also, neck fluff for canines?
3. kind of complicated to talk about but, separating the manes into two categories, primary and secondary, or whatever actually fits, like #2 I was talking about the new manes, maybe the first category would have the 'forelocks' (Mohawks, side mane, etc) and second would have the mane tha- g0sh this is hard to explain, but, like lion manes. I think canines having a neck fluff mane would be really cute!
I'd love to see some extra fluffy bois walking around, and new mane styles too.
