Out of what we saw, the rabbit folk seemed like the coolest design to me. If people with antlers are a separate race from regular humans I think they could be pretty neat too, but I don’t think we really got a good look at them from the front at all.
One thing I did notice was a conspicuous lack of a reptilian race. Really hope we get that - dragonfolk like kobolds and whatnot are staples of fantasy and don’t have an overtly human like design such as elves or dwarves, and given that it seems most of the races are anthropomorphic animals I think they’d fit in well.
(Plus it wouldn’t be No Man’s Skyrim without the Lusty Argonian Maid!)
