I am posting the various steps it took to make the MC battlemap that I just finished for Attack Donut.
The project took about two weeks, but I wasn't working solely on this map. If I had to put a number of hours I'd say 10.
The image is 36" x 48" and was done almost entirely in Illustrator. I took the final image into PS to fix some transparency issues that popped up during the PDFing stage.
I also dirtied it up a bit in PS.
