It already has gone through alpha
Since it has already gone through alpha i persume you were testing the gameplay with bots (am i wrong?), you should generally not test with bots but this thread explains it well:
http://tf2maps.net/threads/psa-dont-test-with-bots.19537/
Also, just below your posts there is a button that says 'edit'. With that button if you make a mistake or something in that post you can change it. Also you can use it to add more information to that post and not have to post several small posts. Just a heads up.
Edit: To get your maps tested with players, there are a couple of options.You can submit your map to be played in a gameday, on these gamedays we play through a list of maps that have been submitted to the gameday thread. On Fridays and Sundays we have gamedays, the threads for them are usually made a day before and can be found here:

The other way is to be in the steam chat (which you can join with a button on the side of the homepage) and add your map with a download link to 'VBot.exe'. To do this you type in chat '!add [filename of your map] [download URL for the map]'. Then, when some people feel like testing maps we will look at the maps on the bot's maplist and play those.
When your map is tested you can find feedback left for it here:

And you can find recorded demo reels of the games played on the map here:
