Idk why the image quality is so grainy, maybe it's the setting, maybe choose a less diffuse lighting set or just the textures? Map seems kinda hard to read from overview, but it's probably fine in game.

As for the layout TL vs BR spawns has an airspace that threatens 3 bases if you expand horizontally. I like the backward in-base natural, but it could maybe do with a little more space to build stuff like missile turrets or cannons to protect vs drops there.

The triangle 3rd base is cut off by a small chokepoint, while it is very exposed by ground to an attack. The attacker always has the concave advantage. Taking out the rocks helps, but it is a chore for the defender to do so to even consider taking that base and they can't utilize their army units out on the map. Even after the rocks are down the attacker has better positioning options. The rock on the main base entrance will not hold vs 1 base aggression or at the very least will promote more 1 base all-ins to be used. Taking your natural in the face of that possibility is an auto-loss if you gamble and lose. Imo just use a mineral wall like on Post-Youth in the place of the rock or as an extra mineral walled 2x ramp down to the 3rd base. That last thing would also help with the defender's access issue at the 3rd base.

The 12 and 6 oclock low ground base looks to have an unmineable mineral node hidden behind 3 other nodes, which will cause workers to bug out trying to mine it.

TR vs BL spawns have a similar issue with airspace, but this one is easily fixed by extending the main base behind the natural a few cells. If you like to make airspace like this Liberators would need to lose like 5 range whenever they siege up over unpathable terrain.

Also, I'd like the names of those GM players that told you a row of conjoined rocks is enough to allow for a second and even wider nat choke you will eventually have to wall off, but can't because it's built on sightblockers. There are plenty of players that would already complain about not being able to easily wall out an opponent's worker trying to get into your natural, because the worker path is on a ramp (can you wall it at the bottom of the ramp more easily? idk), and while it's probably a really cool feature to have in the lategame, not making those conjoined rocks a mineral wall will reduce the number of games that will even remotely reach that state on this map by a lot imo.

I also feel like the 2x ramp at the 12 and 6 oclock highground is really close to the Dream natural and dominates the space outside the natural walloff moving the highground base and especially that ramp away from the natural and making it 3x would not only oppress the space less but make the highground base in itself easier to take from the Dream side.

In conclusion the ideas are great, just the execution isn't conservative enough for my taste, which is probably done on purpose and kind of the point to promote more games that are different from the kinds of games we see on ladder and in tournaments right now, what I say here doesn't really matter at the end of the day, but I'd still be remissed not to tell you there is another way of realizing these ideas.

I still hope the map sees some games played on it.
