I'm about to check out this map. One thing I've noticed most people do is continually update the original post with whatever the newest version and screenshots are, in addition to making replies. This helps people who are just discovering your map get the right version and I think makes the best first impression you can make.
EDIT: Here are some things I've noticed that need fixing.
-It's possible for to defenders to go through A and get up into the attackers' spawn area, right up to the spawn door
-You can spam into the attackers' spawn area if you stand on the middle-most rock formation at A
-All of the connector tunnels are too narrow. Most can't fit two people.
-You can shoot projectiles (and I assume bullets) through the rock formations at C, as well as the big rock between attackers' spawn and A. Doublecheck all rock props for this
-A demo or soldier can jump up to the roof of the building the attackers using to enter A and spam do into the attackers' spawn. In fact, the defenders can spam into the attackers' spawn from a variety of locations
-There is a gap that you can snipe through from attackers' spawn into A, or vice versa. It's where the rock wall doesn't quite meet up with the building
-The only way for defender reinforcements to get to A is through a single, tiny doorway that is easily controlled if you're standing on the point
