I made the tubes connecting the heads with Bezier curves in Blender. I had to download an add-on to cut them where the left head (outside the picture frame here) exploded. Blender gets really sophisticated, and it’s the only program I’ve had to join an online forum to help me get out of trouble in. Usually I can figure stuff out myself easy enough, but Blender is just too big and complex, so you really have to go digging to find even easy answers when you get in a fix. I also added some brackets to the pipes on the back wall, and put nuts and bolts in them.
This piece is going slow because I’m learning as I’m doing. But I’m almost done with the Blender part, and then it goes into Photoshop and ArtRage, where I already know the ropes.
