You've definitely put a lot of work into this,
but I'm sorry to say it doesn't really convince me;
of course I'd need to test-play it to pass final judgement.

Stuff I noticed:
- your deeper water regions only have a few "designated" exits,
this seems intentional - but I think you should rethink that.
For example in the blue-base (see screenshot) the edge could be lowered.

- your passages are VERY narrow - no room for strafing, passing by each other or the like

- you placed a lot of items in rather untypical places,
this also seems intentional ... and again I urge you to reconsider;
most of all I noticed those grenades lying just where you'd want them (behind that half-destroyed wall) ...
... this makes it into a camping spot - might seem funny, but will quickly make people loose interest in playing the map IMO

- your lighting is a too ... contrasted;
it's nice you colour-coded the bases, but you might try working with more but dimmer lights maybe,
to make the transitions a little smoother. Also think about where this light is supposed to come from.
Especially on the red-light-area (heh) you've got some form of glitch - the wall doesn't seem to block the light,
or maybe I missed an extra light entity ... anyway - I see no source/reason for it being there - try fixing that!

So, even if I acknowledge the time and sweat you put into this map - I can't rate it very highly.
I'm wondering who voted this 5/5 ... maybe yourself with an alter-ego login? :-P

thx for commenting.

you're right - some passages are very narrow. i think about it on next maps.
ok, the water areas have only a few "designated" exits.
on the other hand, the community plays currently very often a map (ac_church) who has only one entry/exit point (and narrow, too). so, for many players is this point not a "fun breaker" at all.

in the last days i have done a couple of matches with different players on this map: ctf, team deathmatch and osok.
And it works - so, we have a lot of fun (maybe one of them rated so high, i dont care about it).
the most positive reactions comes 4 the colored bases (dimming - hm, ok - i'll try this).
should be an idea for other mappers ;)

well, i think my biggest problem is to build ladders and walk-through-fence-gates.
but anyway - i'll try it better next time.

and don't forget - this is my FIRST map.

you can rate it five yourself. Anyway, lighitng is a bit...random
Try using /newent light 20 50 50 75 or something a bit darker and not too bright
you can use cyan, that would interesting, using it as a 'water reflection' /newent light 20 50 75 75

Another problem; texture. Can you...get some texture that kind of...not too bland maybe?

Too many people are making desert themed maps, because it's easy...I'm sorry to say, but I've seen 'better' ones like ac_dust

Btw, how did you make the water clear on Assault Cube? it reflects on mine, making shadows...i have to go inside the water to see the colour

<><><>Pretty simple. Get tons of sarcasm here. Then, consider about the sarcasm, use one of it and make better maps. Thats how it is. Theres certainly better mappers than me because they spend more time on their maps.
