Inkwell Ideas is back to releasing a couple of new monster art pieces at a time via DriveThru/RPGNow. Today we have a griffon (http://www.rpgnow.com/product/124370/Inkwell-Stock-Art-Griffon) and a set of four goblins (http://www.rpgnow.com/product/124371/Inkwell-Stock-Art-Four-Goblins-%28Leader-Shaman-Archer-Grunt%29).
The two products above include line art versions... which we've been going back and adding to our prior releases. So far, we've added them to our dragons, dire ape, dire bat, basilisk and boggards.
You can also see our full list of stock art (http://inkwellideas.com/stock-art/).
We hope these products make it easier for small publishers, websites, blogs, etc.
