The map looks good, very reminiscent of Gorge, but the junction comparison is somewhat right. The center point is done well, and is nice and open, but the corridors between the point and resupply have quite low ceilings, which should be raised a bit.
A major flaw however is the lack of a holding area between spawn and the point. This means that if a team is pushed off the point they have nowhere to back out to, so the other team can simply waltz in and spawn camp. There are plenty of official maps that do this, but they're the bad ones, look at Viaduct and Lakeside for better inspiration.
The amount of windows means that it is virtually impossible to make a push without the other team knowing your exact whereabouts. Maybe get rid of a few, or make them smaller.
Finally, I'm worried about the deathpit around the point, more specifically the ratio of point to pit. I haven't had a chance to test it with friends, but I think that making the walkways onto the point larger, so that the walkways are the same size as the pit, would mean that pyros aren't incredibly powerful.
Other problems that I found:
Easy ambush locations right outside of spawn:
The skylight
The stairs straight ahead from right spawn exit
Clip
these on every balcony.
