Now I gotta say I am having trouble understanding the lighting in that last image. The torches don't seem to be lighting up the pillar they are attached to and that the light is going through them and lighting up the opposite side. Also the light flare from the rear torch is showing even though its behind the pillar but I think that is a bug in the app - or maybe an unticked option on my part.
As usual, the textures come from cgtextures.com and I made them (moderately) seamless in the usual way. Its all a bit too clean at mo but whether it will allow me to dirty it up enough I don't know yet. That would be easy to do in 2D but wheres the fun in that eh ?
It still needs some pillars holding up the elevated floor and more decoration. Some of that should be easy but it would be easier in 2D for sure. This is where doing it in 3D starts to hurt.
