These next two posts are for the ArtOrder challenge known as the 'Art Test'. Check out the ArtOrder here http://theartorder.com/. I highly recommend checking it out because it's written by a leading art director of Wizards of the Coast, Jon Schindehette. Furthermore, he frequently posts challenges such as the art test and it's an invaluable source of getting your work seen by some important people in the industry(if it's really good lol).
And here is the link to info on the art test--http://www.wizards.com/dnd/Feature.aspx?x=dnd/feature/dndarttest
