Jackal confronts the Sludge man

I've recently finished reading The Grey Bastards by Jonathan French, and really got swept up in it. I decided to paint my interpretation go the scene that really got me hooked. The half-Orc, Jackal, confronting the Sludge-man, a intriguing and mysterious swamp dweller, with the aid of his new companion the wizard he named Crafty.

Built a basic scene layout in Blender for this piece, and worked in photoshop from there.
