I had no idea what to call this for the longest time and I finally figured it out (hence why it took me a long time to post this one). I did this one back in December, along with a lot of the rest I was posting. This one ended up being for my brother and I definitely have to give a nod or eight to Mario Duplantier of Gojira. I also showed this to one my classes I took last semester.
So as you might sort of know, I do consider myself something of an environmentalist and that's where this came from. There is an explanation behind it, but right now, I may leave that as a blank and let all of you figure it out and post it later when I feel like it.
Done mostly in charcoal with some metallic pencil.
