I'm amazed at how well you got charcoal and graphite to play together. It's pretty light for both of those, too. I can tell you're not afraid of the mixed media combo. It's awesome how you managed to show such strong emotion. I really need to work on that myself. Honestly, the first thing I thought was, "Hey, Gunzet did his take on the troll face."
Now for the next one, I know it's just a concept, but concept art is my favorite kind of art. Yours tend to end up amazing. I really love how you used the green to show contrast the jacket so you could actually see what was going on. Your style is great for this too. It all works together. The extra hand is a bonus. It makes him look even more like a zombie.
Gunz. You may have bad opinions, but you have great art.
