Good job with 1st maps. Lots of places to hide/ run to.
On the final release, you should remove these items from your pk3 to cut down the size.
Extra folder not needed. Remove folder and all items. These folder contains workup files only it appears and your layered .psd photoshop files.
In the maps/dm folder, remove the .vis and .prt files. These were only needed during the compile and no longer needed to run map.
In the textures/mohmenu/dmloading folder remove the .bak file (backup). Not needed.
Why naming the file name with a bunch of preceeding zzzzzzzzzzzz. Make no sense.
Gold is a good teacher or your a very good learner. AA+ for 1st map.

ADDED INFO: To make the map playable by MACINTOSH users, you should include this <mapname.min> file that will be in your mainta/maps/dm folder for that map after you do and run final pk3.
Include this file in the final pk3 (maps/dm) folder along with the .bsp and your .scr file.
