@gregorya I think it would help the read a litte bit better in some of areas, but in general I tried to keep the shading very light. I want my lines to do the majority of the work for these kinds of sketches. That being said, especially the guy on the bottom could use a touch darker values in the nose and eye cavity. Thank you!
Aside from that, here's a preview on what I am working on. I initially wanted to do a goblin aswell, but as I was working on it I noticed that my imagination of a goblin was way bulkier than what Marc had in mind. So, I decided to push it further and made him really bulky, more like an Orc, while still trying to maintain a somewhat believable anatomy.
Let me know what you think!
