Once again this is really only a reskinning of a race, there isn't much actually being changed or added here. There are also a number of incredibly fundamental issues I have gleaned by just glancing at the map:
Both the Coral Bed and the Coral Mill share an Icon and a model. The tidal guardian deals 30+ damage every .6 seconds making it an insanely powerful tower.
The Naga Siren says that it can 'learn' Frost Armor but it starts with it initially with no prior upgrade requirement even thought the unit description implies otherwise.
Troll regeneration isn't even reskinned or recontextualized, its just available in the Spawning Grounds leaving the player guessing as to what units it may benefit.
There are an excessive number of typos from ‘Sea Reveant Grond’ to ‘Blue Dragonspawn Woriors’ prolific through the map.
Finally, having an exact copy of the Demon Hunter as a hero available for the Naga to train in a map that allows for Night Elves to be chosen as a race is a whole different level of scuffed.
Alot of work has to be done for this to be improved in my opinion. It needs some original content, the descriptions need to be delivered from languishing in typos and obscurity, and some real testing should be done on your end to check out some of the changes you've been making. Alot of the mistakes I have been seeing in what is otherwise a very simple reskinning of races could be easily seen from someone playing a single melee match with just one of these races.
If the issues I mentioned are addressed, I will change my rating.
