The blood looks a bit odd. If there's going to be blood the bloog needs to have a sotry, like for instance blood and scratch marks leading into a sewer. Your atmosphere is pretty damn close to Silent Hills looking at that one screenshot so Congrats. However I think the hospital could do with being bigger looking at it.
Also your lighting may be a teeny bit too bright so try to make the shadows bigger, and the light_enviroment a bit less bright.
Other than that I think it's okay, though I'm assuming this is alpha stage and has a bit to go.
I think that brushwork sign doesn't work. I don't like brushwork like that: Props look nicer. If you must keep brushwork make it thinner, so it looks like thin wood. And make the texture a block colour rather than those planks.
Also, if you can avoid HL2 props, do. They look incongruous. Same reason as the HL2 blood doesn't work. I know this is fairly typical in ZF maps- i've found they vary wildly in quality, from professional-standard to not-giving-a-fuck.
