@yubbie: Thanks, those are some great references that I will definitely be using.
@deceiver: I will definitely have to rework and experiment with the colors to get the monochromatic feel of the concept, all while keeping the abandoned/decayed feel.
This was actually my first concept that I did just to get something on "paper" and go from there.
I've also worked on some orthographic views for the the building to help me visualise more clearly the components that I will have to build. With this, I think it'll also help me plan for how I should break down the structure into modules.
I've read this topic and found it pretty interesting (http://www.polycount.com/forum/showthread.php?t=87751
) and I'm thinking I should go with a similar technique using mainly tileable textures.
Also, following this great tutorial by choco (http://www.polycount.com/forum/showthread.php?t=88933
) I've started building my landscape/terrain.
In chronological order:
I've need to blend in some detail textures on the terrain, but I think its a good start.
