Thanks! I created the art 100% digitally with a Wacom tablet and free software Krita. I believe the main brushes I used were 2 different sizes of Sketch Marker Pen style brushes (and then a lot of weird brushes for the textures). I think next time I'll do at least an outline in paper, it's very challenging to go straight to digital. You entry looks awesome, I'll be sure to check it out.
