Looks great, good models. Some things that stick out:
- the wolf is kinda light in color.
- Axe is green.
- hobgobbo could probably sit just a little closer to wolf's head.
I don't think biting action is required, but you may have some difficulties making the axe attack look like it has any chance of reaching an enemy.
As for coloring, I think it looks good. It won't be in key with the archer and sneaky git but I'm not sure if that's a problem. A warrior would wear more armor anyway so a simple robe would look silly. Maybe add some black though. Perhaps the sleeves? It would look like he's wearing armor over black clothing.
