You'll have to forgive me if my limited rpg experience means I'm missing any references. That said...
I really like your style. I think the color amount and placement is a little weird feeling. If you're going to limit the colors, I would suggest using a different color for each side of the battle (don't have green on both the good guys and bad guys).
Also, the main bad guy in the back feels disconnected. Maybe extend the black into the foreground some to tie it in.
Really nice start. Could you help on mine? I should have a new version up in a day or so. The Horrors of Camping
wow!!!! great illustration. I like the color choice of gray and green. I think they really look nice in your design. I would try adding some shadows to your characters, like a cat shadow. it well add a nice touch to your design. just a suggestion. overall great work!!
P.S I just updated my design so please feel free to take a look. I would like to know what you think before I submit it. Again thank you so much!!
