There's too much non-standard melee stuff going on in this map to even know where to start judging it.
If you want to make a melee map you generally want to be very conservative and only introduce a few spicy elements.
Your list is currently too big:
-Shipyards
-Mana Fountains
-Asymmetric spawns for each player on a team
-Non-standard creeps
-Too many merc camps
The reason why a lot of these features are not good or controversial is usually because they're not fun.
When you play competitively you want to play against your opponent not the game itself.

You're not terribly off on how to make a proper melee map like i see with new melee maps, so you have potential to work with.
I think you just need to look at what other successful maps do and take inspiration.

I highly recommend reading Mafe's guide for some insight into what goes and what doesn't when it comes to melee maps.

This doesn't look like Black Sea of southern Europe.

I don't think that was the idea?

So, there arent any real bugs or mistakes in this map. The itemdrops and creeps are good here. However, @Nudl9 already mentioned some potential downsides, which I agree with.
Some other stuff that imho isnt perfect yet:
1. It is very hard to recognize where there is water (and therefore boats can move there) and where there isnt.
2. The defenders advantage is really strong, as the attackers always have to move up a ramp when attacking a base.
3. The creeps in the middle might accidentially get aggroed by player units and kill single units. It's kinda similar to LT or Market Place. I dont like it, but I guess I can blame you if there are successful maps that also do it.
4. There should be more space for buildings near some expansions.
5. Many dead ends again, which I think are not good design.
6. Visually, there is a lot of room for improvement. It's just abuot acceptable because of the size of the map, and I personally also cant always force myself to polish the looks of each map

So while these are not bugs, I think they really can limit the fun of playing this map. This is somewhat subjective, but looking at which maps are popular, imho the general wc3 public seems to wrong. Nevertheless, map approved as technically it is alright.

Nice Map Dude
