The map is lacking in overall quality.
Terrain: The terrain wasn't too bad. You had some tile variation, but I'd like to see more.
Doodads: Some areas looked nice as they were matching the environment. But sometimes, you placed doodads from different tile sets such as sunken ruins doodads. This simply looks odd when you do that kind of thing.
Balance: Melee maps do not need to always be symmetrical, but they should have equal distance to resources, shops, and creeps. You don't have any of it.
Layout: The map only has skinny pathways. This results in minimal strategy.
Your description is also high lacking. Please read our rules. Map rejected, I suggest you read melee tutorials.
