good work so far! on the textures i'd suggest looking into uv-reusage though. your textures seem to hold a lot of information that probably doesn't need to be unique (or could be uniqui-fied with decals) and you'd save texture space and probably get a faster progress that way.
Okay so this ended up getting left for ages while finishing uni. Start back on this yesterday. Worked on how I might do the lighting, then rolled that back for a more neutral scene while I worked on some texturing. Most of the textures are tiled, so I'll be using a bunch of decals to add interest. Nice to be working on it…
