I'm a little bit shocked when I saw the map. Most of your maps are very nice and good mapped and I really like them, but I never thought that you would fix a leak with adding a skybox around the map... This is horrible.
I would also like to see more source lighting instead of light entities. The colored light entities are ok, the other ones are very bad and looking ugly imo.
Add a "_sun_angle" "# #" if you are using sun lighting. I don't know a good value for this sky, because it's new for me. Try to figure it out by yourself. Maybe it's easier to set a higher light value for the time you search the correct sun angle.
You should also think about adding clip brushes all over the map.
Don't use water surfaces at different heights.
Please add "angle" "#" to the player spawns.
Hey, come one, it's not your first map. Put a little bit more effort in it. Also you should really try to improve and finish some of your other maps before starting map after map, you won't ever finish. Working on 10 maps at the same time can indeed do not go well.
I'll post more detailed feedback and screenshots after you fixed all of this stuff.
