Well, my opinion is: let it die, forget it, wait some time and start a new one with a new theme. I don't think there's anyone really interested in this project anymore, and after so much time even I lost interest in it. It was started in a wrong way, and imo a bad theme was chosen, with everyone having different ideas on how should it really look like. Besides I'm tired of seeing those blue textured tiles already. My style has changed over time and I don't use textures anymore, I don't even like them. Some things in the basic tiles of this tileset were solved in a wrong way what makes it hard to predict what tiles which didn't get added yet are necessary for it to be usable. Sorry, I just don't believe anyone can turn this picture into something good anymore.

I wish the LMAT team focused on finishing Agama's Prison instead btw.
