Ok well, I guess this is not an entirely serious map. Instead, it is a "concept map" where balance and playability are secondary objects, right? At least that's how I'm going to review it. So:
1. I have to say that the map has certain visual appeal, in this actually because it uses only a limited number of doodads. Definitely looks a lot like those moncake, which I've never heard about before

2. For the layout, having a land connection between the left and right half of the map would still be good.
3. Dont have creeps randomly drop items of different levels.
4. Main bases are in very weird places.
To be honest, I dont think it makes sense to go into more details.
Still, as large maps are a lot of work, and I like the general idea, map
approved.
