I liked it, it seems like other maps created by Blizzard which are more turned towards the classic style of RTS games in pvps or player vs computer.
I'm more into Custom Campaign, but this map provided me fun for while it lasted, I would point out just one thing with the enviroment that I think you missed, it is by the right side of the map, in a murloc creep camp, there's a difference of elevation there which I think was misplaced, some troops of mine got stuck in this area but I managed to get them out, just so you know if you want to change it in the future.
Congratulations on your first map and keep going!
