hm this is my first goblin , and i think he´s not so ugly ^^ base in work , this red dot in his face is his tongue ;D can be seen from another sight/perspective ... pls comment
Like Katana_angel said, another layer of lighter green on the skin would make it better. I really like the choice of the moon on the shield being black(and it's painted very well too btw) it gives it an evil look, though you might want to give the rest of the shield another color for contrast. Not bad at all!
Well, he's looking pretty good. The shield is nice, but maybe his skin could use another hue of highlights. Also, take another picture at a different angle so we can see more of his body/clothing. Keep working at it. :)
