Pros: Great map, one of my favorites. Excellent layout, design, appearance, and style. Thank you!
Cons: Not many... no wait... none!
Improvements: When the easter egg is activated, the player that activated it has low grav until map change.

Nice i enjoy it there's a glitch on one of the boxes if u jump on the side u float around for a while other than that ghreat

Pros: The first thing that strikes you are the lighting. It shows that you put in a lot of work into it. The red corridor is definitely a favorite. It looks really cool.-
The custom props are a nice touch to the map.

Cons: The lighting. Although it is looks cool it doesn't really feel in place. The light is too yellow to be realistic imho also the mix of "warm" and "cold" light makes it look odd in places.

The routes to the inside bombsite becomes crammed when you increase the player numbers. We played this map 8vs8 in our LAN tournament and already at those numbers it was an issue when rushing.

You are using many standard textures and props and that means also that the few things being remembered from this map is the lighting and the red corridor, at least from a mapping point of view. What I am getting at is that there isn't a "Rio football field" in the map. The crane is very anonymous in my point of view and as it is the name of the map it could more used. For example lighting it so you see it i.e. making it an eye catcher.
Another example of this is the inside bombsite which is anonymous except for the custom missile (which I love!) and I am confident that you could have done something more with.

The layout makes the gameplay predictable. At the LAN tournament this became extremely obvious with Ts rarely losing more than 1 or 2 rounds. We had this map in the rotation but it was removed. I think it is a tad to linear.

Improvements: I would suggest to broaden the corridors leading to the inside bombsite or adding yet another route.

The light is something also I would modify. However, I guess it is down to personal preference and what you aimed for. I just don't think it fits.
Notes: Looking forward to the next map you make.

is it the same vesion?
really nice map man looks awesome, did you primarily plan it for 5v5 scrims or for 32 players?? do you think it could handle 60, 64?? or are there so many nice features it would begin to strangle the fps a bit

Stunning !!!
