Cavern Troll Concept Art

Here are a few process images for how I usually create a concept character piece. It's my take on a popular fantasy character, the troll. First I started with a traditional pencil/paper thumbnail sketch then translated it to digital via photoshop and sketched over it. The next image is the value painting where the form is refined in gray scale and the lighting is decided upon and blocked in. Lastly I used some color overlays and further rendered it to eventually create the Final image.
