I’m guessing you probably already saw this avatar, but I genuinely couldn’t find a better substitute, even under similar keywords for “goblin”. Of course, I think this is actually built from WoW pieces anyhow, so that may be why.

that being said, it looks like you could edit the skin, and I can certainly go look for some eyes and hair. I can’t see how it would be compatible with another body like the one you mentioned though, sorry. Reviews mention altering her proportions like any other avatar, so maybe you can mess with the sliders to make her as fit as you need? Good luck in any case! Goblins are the best.
