Vampire Trenchgun, WIPs

I love Hunt Showdown's alt-history theme and weapon skins and variations. Based of the Winchester M97 "Trenchgun" variant, here's my own inspired piece as a priests anti-vampire shotgun.
My Substance license expired while texturing so I have limited renders and consider this WIPs.
I want to take the concept further where reasonable. Make it look more dangerous. Reinforce the idea it belongs to a religious man without just adding more crucifixes. Add more wear and tear without plastering dirt over it.
