Hey bakr, this looks like a really cool model!
Could you make another version, with the following things below?
1.) Tinker Rockets for Mortar Shells (shells that shoot up like bottle rockets and could attack air units too).
2.) The third goblin that wears a barrel of said Tinker Rockets.
3.) Their Ka-BOOM ability, when they get swarmed. (Simply have one of the goblins hit the rocket on the ground by their primers (back ends) and have them throw the entire shell on the ground at their feet.)
4.) Make it something like a Neutral Building Explosion, but more like a critter exploding, with heads and body parts flying all over.
