I know TheTalkieToaster is making some playable goblins which will be much better than these since they use creature skels etc.
But for now here is a WIP of some playable goblins I am creating:

So far I have 4 different "hair" heads (so no wearing helmets) Regular, skull, skull with horns, and leather cap.
I also have completed hands (gauntlets/gloves), and Feet (boots) for a little more gobliny look.
I intend to do more with this I think but for now enjoy the screenshots
