Chewie, first off, your torture chamber looks great. The lighting and the color makes it looker really creepy and gives it a great underground chamber feel to it. No wonder the Rykrof looked the way he did in your preview pic of him.
The cell guard look pretty good, but to me the torso still says Dengar. But I think the Dengar body was a good choice, I like the idea of the guards having body armor. Maybe if the colors where a little different.
Now, Mubaas Fuuda is one cool custom. I think this is one of my all time favorites of yours. The use of the Sahara head wrap adds so much to this figure. With the weathering, the wrap makes the Bib Fortuna head look very unique and drawns the attention away from it being from Bib Fortuna. Great Job!
