Those look just great! I like everything about them, and especially how the kitbashed arms worked on the goblin bodies. The Gripping Beast spear arms give that ‘about to turn someone into a kabob’ vibe, and the gnoll arms on the leader… beautiful!
I’m curious about the standard - I recognize the beast skull on top, but where are the human skulls and hair from?
For what it’s worth, I like the shields and inspiration from the feoderati. They look very orc-ish painted in the black and red palette and kind of fits with orcs/goblins serving as foot soldiers in the armies of evil empires.
