Pros: mm nice idea not many dev texture maps with more than one story high.
Cons: i dont really like the blotchy lighting it looks like its ceom from no were.
Improvements: could add some lighting fixtures or props to make the lighting look asif its coming from them.
Pros: Great texture map... Nicely done.
Cons: None really. Even though you don't use light models or cone shapes too contain them the lighting still looks good.
Improvements: Maybe create a bulb or something out of one of the dev textures so you don't have random light spots.
Notes: Epic at it's full awesomeness -1. (Hence the 9/10)
