Oh cool, wasn't aware it was a three part thing.
I love the small cute version. I also like the tall elegant version. I've really come around to the idea of having tall/elegant females and short/cute males. Correct me if I'm wrong, but although there are male viera, we've never actually seen them, right? So I'd be ok with the males looking short/cute like in the concept art. I'd probably change my main to a male viera if that was the case, and I'd make a female viera alt as well.
On a side note, not too long ago I learned female rabbits tend to be bigger than male rabbits of the same breed. Not saying that viera should necessarily reflect the reality of how real rabbits actually are, but it was just a fun thing I found out.
