I believe your .cfg texture path is wrong. You've got "exec packages/texture/nieb/package.cfg" when it should be .../texture"s"/nieb/...
Also you might want to concider the texture you've used for the flor, as it reflects the skybox, looking sorta weird when you have a wall in front of you and theres parts of the skybox being reflected ;)
Other than that I really like the retexturing. However the old texturing made it appear somewhat "dirtier" this is now very clean. It also no longer really looks like a "metal" city, so you might want to reconcider naming it?
Gameflow's pretty awesome, texturing could be done better, overall appearance is great tho.
My 2 cents,
