Pros: Well detailed and optimized, design and layout for the most part is good, plays well and plays fun.

Cons: The second point on the second half is overly biased toward Red, 3 engineers can almost completely lock it down. The tight nature of this part makes it difficult for blue to get shots off on the sentries and push in.

The 3rd stage could still use a bit of re-working, its a bit too open, a few more props and structures here or there might be nice to break things up a bit.

Improvements: Check your underwater displacements on stage 2, a few of them let you see out to the skybox.

Open up stage 2 cap 2 more to make things easier on blue, maybe add in a one way door in the upper flanking area to the left and add some metal up there for engineers to get a teleporter up more easily.

Another option for stage 2 would be to add another flanking route that lets blue get farther behind red, but I'm not sure how much it would help without opening up the area.

Make a custom explosion for the last point, not really a huge necessity, but its a nice personal touch rather than copying valve's cinematic explosion.

You need a tad bit of work on optimization on the very last point as well. Notes: brbuninstalling.com 24 man custom map night play test

Nice work, look forward to future revisions
