I've checked out the map and it's just what the screenshot shows, nothing well.
The theme isn't clear to me. Be sure it has a theme.
The texturing is pretty bad. A lot of textures aren't fitting the geometry (like those round "houses") and the map definitely could use some more textures (which also really match each other).
The geometry isn't great also. There are a lot of geometry errors (like those weird own-constructed trees that have a scrolling "5_blood" texture on the geometry).
Only the landscape itself is pretty good, but it looks like you haven't made that (if you look at the other objects in the map).
The lighting isn't great because the hole map is lighted, but there are no light-sources. The light comes from nowhere, which gives a very unnatural feeling.
The detailing is bad because there is almost none.
The clipping/noclipping doesn't exist here. Too bad...
The flow is 1 of the better points in this map, but everything gets played on the same level of height, which screws up the flow.
The gameplay, isn't great either. Pickups are placed on pretty unlogical points and the amount is just way too low for such big map.
Overall, I'm sorry to say but this map is a low quality map. Be sure to create something better next time.
