The triggers aren't really advanced, and have position leaks, which wil make the map lag over time.
A template doesn't need to have triggers in them, your main focus should be the terrain.
Talking about the terrain, I can't say I'm impressed by it. I don't mean to be rude, but this looks worse than dotas terrain. :/
You told us that you spent 7 hours creating this, and that wasn't even all on the terrain. Most templates takes people several days to complete.
I suggest you put more energy into the template, as I doubt many people would want to use this over creating a terrain themselves.
Additionally, if you keep you add your own heroes and such, why not make it an entire playable map instead?
