That file you uploaded was super helpful. I intend to start work on it soon, but before I do I really need to ask a question!
Firstly, by looking at the walls in the Solitary region, it looks like the texture is just a 'repeated' 64x64 brick texture. It doesnt link into other bricks, and has a somewhat un-natural feel to it. If you prefer I could create the tiles texture EXACTLY like in ST, or I could have it take on a more natural building form of bricks linking into each other. Im okay doing it the ST way.
The relief sections are quite detailed especially the figures on the roof section, recreating them in high res would take time if I done it right.
What pieces do you not mind losing? Ill have to overwrite certain map piece parts. This will affect future users of the ST sets too. No pressure
Heres your first ST shield. Done a speed method on it and it only took me an hour to model and texture. Yup I drew everything as usual.
