It's incredibly difficult in this state for armies to attack into the natural due to the two narrow chokes.
Zergs cannot wall the natural choke.
Macro maps are often categorized with a very easy to defend third base, this map feels more suited to Standard in its base layout, but it has an incredibly long (too long, imo) rush distance.
You're missing an unbuildable plate at the bottom of the main ramp.
The natural can be sieged from the lowground third, and the distance (and the choke) to get to defending it is too extreme.
Most of the map is in narrow hallways, making it difficult for most armies to engage in any favorable manner without dying to splash or mispositioning.
I'd recommend avoiding making the large pockets of deadspace.
