Some time ago I was hired by Run Amok Productions to create a number of quarter page, grayscale illustrations for an upcoming RPG book. Now that the book has been published, I can share both the images and the link for purchase. This is a D20 based book, so can be used with a number of games, predominantly D&D.
Alvaro Snegg & the Bellringer Brothers

Alvaro Snegg is a formerly living spell caster, who died and became a creature that is composed almost entirely of writhing worms. His present form makes him nearly unbeatable in physical combat. A trait which the Bellringer’s, a pair of pit fighting champion brothers, have been using to their advantage.
Captain Ahbram and the Freebooters of the Cacophonous Chantey

A ship containing a monstrous beast deep within it’s holds, teeming with a crew of deranged madmen, and Captained by a vicious cutthroat of the pirating seas.
Matsuyo and her Snow Yeti Twins

Matusyo is the spirit of a deceased samurai warrioress, who is revered as a god of sorts by a pair of brutally loyal twin yeti sisters. The trio exist in the cold snow covered mountains, and guard their territory fiercely.
Boughbrother and the Satyr Slayers

Boughbrother is a treant who has been driven to maddened bloodlust by the intrusion of humans into his forests. Along with the merciless band of Satyr slayers, he preys upon any party misfortunate enough to have caused damage to his lands.
Definitely was a fun project to work on, with a company that I look forward to creating more images for in the future. If you are interested in either downloading a sample or of acquiring the full book, simply follow the enclosed link.
