+1 for more long hairstyles and more creative ones, but also...
I'm gonna say what I say in every thread: More. Updos. Cute updos. Elegant updos. Messy updos. More! Updos!
I get that a couple races have a ton of them, but the others have barely any (or they're "half up" like the twin buns sadly are). Updos are a solution to "omgz we don't want clipping!!" and for those of us who want their characters to at least not have short/med hair, we can imagine it's whatever length we want, just pinned up.
(P.S. I'm still dying for female hairstyle entry #16 T_T)
