I just did a quick walkthrough of the map and I like the idea of it being a quite vertical map, but I just find some areas too small and cramped.
I really like the mid but I think that house shouldn't be so close to the point. I'm not sure if a totally symetrical map would work very well honestly, not only because it's quite confusing since everything looks the same but also because it leads to having very small space for variety. I think you need to give different advantages to certain classes on different places of the map.
That's why in 6s there's a flank and a choke, because in flank, some classes are better and on choke other classes are better. Even if you're not making this for 6s, I really think you should consider changing some stuff, you might be able to keep 1/2 of the map but you need to change the other half.
