Not gameplay related, but instead of labeling it "beta" you should keep track of the version number (if you aren't yet, if you have the version number saved for yourself, then ignore this.) If you keep old versions, you can look back on them for reference, to undo changes, and in the worst case, recover something you deleted that broke the map.
Version numbers also tell subscribers at what stage development is at.
This video by a very talented map maker explains it.

Looks like a good first map. Next time, some more variety with visual details would be good.

I likey

but maby add a mountain sor something in the backgrond because it looks a bit plain

Looks EPIC! Great job, lots of fun. Please work on it more!
