Fog didn't work on mine.
These are my two versions though. I think i'm leaning towards the leaf one with no grass. - because around the tower everything is dead. Even though its thick forest elsewhere.
Thick fog may make yours look interesting, i'd definetly try it. Oh... can you change the eyebrows? i think that may be part of what is throwing me off. he looks to happy :3
otherwise its the vines that i feel are out of place. maybe the rock on the other side?
