Very nice model, and cool lighting too - very dramatic 
He reminds me a lot of the one main orc character in Warcraft III, Thrall. Even the lighting is reminiscent of the lighting in some of the final cinematics of the game.
So you’ve certainly captured the orc vibe, so to speak.
I can only really think of two crits to add to what’s been said, and that is that the skin looks a little too dry, and almost flakey. It could also benefit from a teeny bit of translucency, perhaps, especially on the ears 
On a side note, I’ve heard that Blizzard aren’t crazy about receiving orcs as part of peoples showreels. I read somewhere that they have said something to the effect of “We can already make orcs, show us something new”… maybe that is something you should ponder, eh? 
So by all means, put this on your reel, but I would suggest making quite a few new characters of your own design that feature prominently in your reel. You clearly have a good range of skills, and that is what Blizzard do prefer - good all rounders, as opposed to specialists. So show them a wide variety of what you can do with those skills - good luck!
