Hey, nice map you got there, here are my thoughts:
1) Visuals are very nice, I like your work
2) To be honest, I agree with
@Nudl9 that your map is not suited for boats as there is no reason to use them really
3) Ramps, ramps, ramps - While it is a beatiful eyecandy, there are 8 ramps per player, most of which are a hard choke to fight on. I would reduce no. of ramps to 2 or 3 really wide ramps
4) Outer paths should be wider, they are 1 yellow square wide in most places
5) Both nearby green camps have poison, are lvl5 and drop +1 tome, - I would make one a tad stronger and give lvl 1 perma
6) NE AoW creeping seems lacking? That lvl 14 orange while doable is rather hard and risky, lvl 10 murloc seems too far, idk
7) Drake at shop is a rather unusual thing, not sure how some melee armies feel about it since it forbids them from buying half of the time
8) Item drops are good, only one which seems odd is lvl 2 perma + 1 tome at lvl 14 orange
9) Some camps may agro, but they are not on the main scouting paths so it isn't as much of a problem as usual
10) I like the middle, it is not only visually pleasing but also gameplaywise interesting, only thing which is missing is something to fight for
To be honest, this maps checks all the boxes for beeing considered a complete melee map, it just tries too many unusual things (boats w/ questionable use, highgrounds everywhere, kinda empty middle) which some players may consider unwanted. Nevertheless, I would still consider it as fully playable and leave it up to you to decide if you want to keep it this way or change it.
