A fairly well done greyscale illustration for a rust monster with a pretty straight forward license regarding commercial usage. A deal at the price for a publisher needing to add art for this particular creature within a PDF publication, or on a website. Perfect for home GM's as well.
Can think of only two things that would have made me happier. The background being on a separate layer to give the option to not use it, and a copy of the image in color, but color would have raised the price, so that one I can understand.
