Sorry if I'm a bit blunt, but here's a few things you may want to consider if you wish to get this map seriously approved.
Don't say "Now with Triggers", it just makes people look down on it. It's like saying this car "now has an engine". Unless it's a melee map, it's supposed to have triggers.
Creeps look like they were just randomly placed, especially in the middle.
Tomes of Power say you're a great map maker? Show it, don't tell.
Lvl 1 Blzear made hero? How about Lvl 1 Keeper of the Grove or something more professional?
The Nuclear Strike creates HUGE LAG. I was doing single player and I lagged for like 15 seconds.
