Alright. Final post in this thread. If you completely ignore it, whatever. You miss out on criticism.
Your changes have been purely aesthetic. From your self-proclaimed Beta 1 to self-proclaimed Beta 3, I have seen nothing changed but aesthetics. And don't you dare say I haven't played your map. Because I have. I would not be giving you criticism if I had not played the map.
The map suffers from long corridors and odd attempts at making it seem better than it is. The community you are sending this out to is rather limited, and the only people you are listening to are people that have given an overzealous caps-lock reply on how it should be made official.
The people you are appealing to have little to no knowledge on the creation of maps, and should not have their advice be put before ours, the mappers.
What you should do is focus less on aesthetics and worry, yes, worry about your dwindling gameplay. As your betas go on, you claim you are changing various things that would have changed gameplay chokes and hiccups from previous versions, though, as stated before at the beginning of this critique, you have not actually made these changes.
It's not too late to revert to an Alpha process and rework the things you've said you'd rework! If you keep up the aesthetic changes each time you release, you'll have more and more brushes to change, more and more entities to nudge, all of these things you'll have to change in order to maintain an efficient and effective map.
So please consider this advice and don't turn into another outburst of rage and bore...
