Something that jumps out to me immediately is it seems like no matter where you are there are dozens of angles you have to watch out for which can make the gameplay feel very overwhelming. In addition, there seem to be multiple paths scattered everywhere (a few involving parkour elements) which could also feel overwhelming. If you compare it to Valve maps, they have very simple layouts overall but feel like they have more depth due to visuals.
This may just be my personal taste but bombsite A feels very difficult to retake as there are a lot of long and parkour involved sight-lines that can lead to even a single T waiting for a defuse and taking a cheap shot. B site could use some more cover on the plant area but without a smoke grenade (and even that you can spray through it) it seems very difficult to defuse on either bombsite.
There are also a lot of tight areas, one being going into A site which could be very frustrating to play with when you have a teammate blocking you. I think you could have an interesting mechanic forcing 1 by 1 using tight areas but i'm personally not sure this is spot for it. Molotov's and smokes spread quite far so you can open up these areas and still give players the ability to cut them off.
Lastly there are a lot of random corners that seem to be there just to camp while getting cheap shots off. I really don't like that hiding spots under the double stairs for example, it just seems frustrating to play against.
Anyway, take my opinions with a grain of salt as I'm no expert on any of this.
