Well, my crits are kindof petty, so take them with a grain of salt
The title stated "Old Deserted Building", so I was under the stereo-typical impression that it was going to be old, dusty, rusty metals, crumbling cement or brick, with a little bit of dust haze hanging about in the air, ..that kind of thing.
But yours looks like "almost" new, as if the tennants just moved out recently.
Also were you going for that bright sunny day look? ..or were you looking for the gloomy basement kinda feel?
I ask because some of the objects as well as the joists do not have the stereo-typical "contact-shadow(s)".
Like I said, this crit was kinda petty, so ignore me, because I don't know exactly what kind of image you have in your mind
GREAT shot though!
