Are ALL Orcs Ugly?

I am actually asking this question in all seriousness.

If we watch the WoW Intro Cinematics, we see some pretty ugly and brutish looking orcs who don't seem to have much intelligence or cosmetics... Then we see fanart of orcs that can all favor the orc who is being drawn. But from a Blizzard perspective, did they make their orcs to be ugly creatures?

We know Garona has a pretty face, but she's also half draenei.

Another official orc from Blizzard Entertainment:

But then we look at Blizz's official artwork, and I can say that Thrall is a pretty damn good looking male orc with his pretty blue eyes and muscles :P

So really I am just wondering... Are orcs (the World of Warcraft orcs, I could care less about others) MEANT to be ugly and barbaric creatures with no hope of making America's Next Top Model? Just curious, this topic has always confused me.
