Looks great!
The name could be different, I mean this map doesn't seem to have anything to do with blood or a river...
It looks like there's a river in the third screenshot.
I'm going to run around in the map and see if I can find any glitches, I'll update this post if I find anything.
Edit: There are a couple of things I found that will cause problems. I didn't take screenshots (sorry) but I can describe it all.
1) The whole map is in one big box, so when you jump in the area with point C, you can see the areas with point A and point B, and vice versa. If you (I think) add brushes with the skybox texture so that the map is in 3 smaller boxes, the map should run faster when a lot of people are on it.
2) The water tower near point A needs to have a playerclip brush all around it. Right now you can jump up and get stuck in it.
3) The building containing point A has some windows at the top. Those windows can be jumped through. They also need a playerclip to stop that.
4) The exits from Blue spawn on the B side have a tiny lip that a Red player can jump up to and stand on, and all the exits from Blue spawn do not display the "No Entry" sign (
looks like this). I expect that you'll need to revise the layout of Blue spawn after you test it in a game but I don't have any good suggestions for that.
5) The exit from Blue spawn on the A side inside the little building needs a playerclip; people can jump up onto the roof of the little building.
Aside from these the map seems pretty good, but you'll need to test it with some players to get the really useful feedback.
