That's a well done project to start with! How did you make the back/armrest? Is it modelling clay like Green Stuff? I really like the paint on the throne. Some pigments and/or a shade would give the plates even more depth and make them look like stone. I made good experience with this technique.
Thanks for sharing! Your post inspired me to get the SOTDS Jabba with Throne, which I recently found in the bay, out of the box, again...
