I made an edit to the concept art

I made the shoulders less broad, the neck a tad bit shorter, and removed the fur.
I think this is a good body type for male viera

As long as the male viera are slim, and just a little bit shorter than the female viera, I think that would be cool. The female viera are pretty tall in general, so even if the males are a little shorter, they'd still look cool. In my opinion, I think omega m body type is a good in-between for people who want a more buff viera, and for the people who want smaller viera.
Another option would be to allow a max height male viera to be taller than a max height female viera, and have a minimum height male viera be shorter than a minimum height female viera. Or, the height differences for the subraces can be different.
