Great looking creations. Personally I would love to see some knee articulation in your modified Mutt, but excellent use of soft goods here.
As for your dianoga, just great creativity here. It might be cool to cover this black tape with some type of colored fabric (thinking of something like Sjefke used for his great Cane Addis) to get the color to be a little closer, but when I saw you Tatooine Hut I guessed what it was right away.
