I am rather newbish at modeling and noob at texturing. For a few weeks I have been trying to make some buildings inspired from Oblivion (the scify movie) and perhaps Elysium. What happens is, I start modeling, and at one point or another it gets crappy. At the end I am unhappy with the result, mostly because I would need reference images, not concept art.
What would help me loads would be some models in this nature, preferably textures, so I can study them and form a mental process on how to create new things of this nature.
