I believe a great part of the community would like to see humans on Yiffalicious, as it's been discussed for years now. And now with YL2 and it's character builder, I believe it's the best time to implement it. Because all that's left in it is the human head and feet, as we already have the rest.
And with it, we'd have the liberty to expand beyond just humans, and customize them to make other species. Like, for example:Neko Girls:
(which, by the picture, reminds me that heterochromia would be a nice additionElves: (humans with pointy ears)

Succubus: (elves with horns and wings)
and, most importantly, we could have Humans x Furry
