Male worgen have somewhat of an update we can look at with Genn. That artwork for the female worgen looks rad but we'd have to see an in-game model. Like people have said hearthstone winds up looking a lot stylistically different from WoW.
Just looking up "female worgen" it's almost entirely "here are concept arts for better female worgen blizzard" or "look at how derpy the female worgen model is blizzard"
But considering the makeover female tauren got I have confidence they can make it work.
This one's not too bad. A little more wolfy, shaggier.
whereas this one tries to lean towards the more feminine angle. Also promising.
But regardless of the approach everyone universally agrees
something must be done.
