You may all remember a few years back when I had an old piece of GW terrain, laser cut. If you don't, go take a look,
here
So, fast forward to today, and with the aid of a die cutter, and some thin card, we have the following. Necromunda Tunnel Entrance.
Just the raw card, assembled with the GW bulkhead.
I went along and added rivets (252) and a few resin detail parts (Pardulon and DragonForge)
And with Paint. Base was textured with a mix of Vallejo Oxide Paste and Black Lava.
