this was some random model in my friends library . bicycles were pretty high res so spend some time to optimize them . i am not a good modeler so well didnt worked very well .
lighting . hdri map
materials - just shaders on cyles . on the wall there is mix material with normal concrete mixed with dirt texture and a color correction node for that brown look
upper glass was simple regular glass
lower green glass has a low glossy value
render time - well after 16 mins ( 55 passes ) it was fine but there was little grainy so i let it run 100 passes ( total 26 mins )
