Here is my finished “hellcannon” model. I used the Cygor model from M.S.G. for the hellcannon.  I modeled the flames out of green stuff with a metal spawn model coming out of the flames, like they’re being transformed by the demonic sorcerer as the cygor is throwing the spawn onto the enemy.  That will cause a panic check!  🙂

The demon sorcerer is modeled out of a black orc banner bearer with a demon prince head and a tzeentch hand holding a book.
