The Horde feel no Fear

This is my entry for the Heroes of the Storm contest !
Big fan of Thrall, I wanted to show that even the Lord of Terror cannot impress the Warlord of the Horde.

I used pencils, 2H and 7B to make the grey tones, blackink to do the strokes, and photoshop to make the lights, thunder, and to generally twist it better.
I used "photoshop enhanced pencil" because I wanted to do something a little aside of the "speed painting video game style", closer to graphic design, like a poster. My first attempt with this approach and surely not the last. 
It's my very first illustration contest, please feel free to give any feedback.
