well.. if you think it isn't worth it, then don't do it.

My intend wasn't to build the best map ever, but to have some fun playing around with cube. If you don't like what i built then that's completely fine with me.

So what do you expect how one should you react to your comment?
"Oh my map isn't as good as others, i should stop to build maps!"
or more like:
"I build crappy maps, i should start to build good ones"

Either way you see it, the point remains that content is usually most of the time expected to be of good quality :)

Personally I would say the second statement, but it's not about what I think in this case (neither anyone else actually). Quadropolis is mainly intended to share wisdom, creativity and many more within maps, mods, scripts, models, skyboxes and many more content; instead just dumping the map on Quadropolis and hoping for some comments of how to do something better or just on a different way (which fits the wisdom part).
When a content is just of such low quality compared to the stuff which people are mainly seeing, then it's not very plausible people tend to check out your content, as it looks worse as average from the first sight already. That's why I suggested you to observe other maps to get an indication of the requirements of how a map should look like today.
