Okay, I get it; they're supposed to be big, burly "strongman" types.
But fact is, Kul Tiran males look fucking *ridiculous* from a side angle:

It just fucks with their silhouette too much. Not only are their bellies MASSIVE, but it looks almost like they're trying to sneak a basketball under their shirt, it looks freaking awkward as hell.
Couple that with the insane texture-stretching, and you've got a problem. It's no secret that "armor" is just textures being placed over your character's body, but here, it seems to highlight that to such an extreme, it looks more like body-paint than even presenting the ILLUSION of wearing "armor".
Keep them "big", husky, whatever, but just tone down their gut A LITTLE BIT, please Blizz? If they weren't SO fat, I can see where they would cut a little more intimidating frame. You wouldn't even have to change their skin textures, as they can remain "well-padded". Just don't go *so* extreme with their weight. Like I said, in its current state, it just looks ridiculous, especially when wearing armor. Toning it down just a bit would do WONDERS towards making them actually seem even remotely "cool".
Extra points for bumping their shoulder-size up just a bit, and increasing the size of Belt "ornaments". Oh, and I would really dig some additional Hair and Beard styles, maybe more "viking" styles? After all; we're clearly not getting Vrykul at this point, so at least having a couple of full beards and braided hair/beard styles would be excellent (while also fitting the naval theme of the race, bordering more on "Pirate").
