New Metalocalypse Artwork!

I was recently contacted by the Cartoon Network staff to create yet another illustration for the cult heavy metal cartoon, Metalocalypse. I’ve included the sketch and final artwork below. I believe the illustration will be used for an upcoming concert event poster, much like the one I did for DETHKLOK in 2007.


Devourment Sketches

I was shuffling through some artwork to send to Norfolk, Virginia for an upcoming art exhibit when I came across some initial sketches I created for the DEVOURMENT T-Shirt. I thought I’d share by posting them here. Enjoy!
