This map is better than the botmap
It's very important that you don't ignore the errors, warning, etc.
Your map leaks, because you forgot the (sky-) brushes above the map. And the wall of one small way isn't big enough (blue base left out; behind the blue door left). There is also a wrong placed white corner in this area.
You can see a few more warnings while loading the map. Delete
giveweapon carbine from the worldspawn and use
loadedco2 large instead of
loadco2 large.
Now the lighting. Don't use
light entities for the general map lighting. They are looking horrible. Texture lighting or sun lighting (lights with sources) looks way better.
And I am a little bit confused about the gamemode. You wrote pong, but the map is single flag and too small for pong. I think single flag (as the mapfile is) is more useful.
Maybe it would be better if you use our german clan forum for your first maps. You can find a german bsp mapping tutorial there too. Have a look at my signature for the links.
