Chaotic stream of consciousness doodles, in a good way of course!
That, and the description finally answers one of the questions I've had about your art for a while.
You draw very heavily with markers and pens, so then you use sticky notes to cover up 'error' sections and then draw over it, making the page/background a mosaic of coloured squares that I thought was plopped down from the start.
You also get pretty good mileage out of the pages, adding the tiny doodles nearby the much bigger focused characters, which explains how Scrimblo came to be as he keeps making cameos throughout the pages. :P
Interesting stuff!
