Hi and welcome to the forum.
off to the less pleasant matters: Your image. This is not a beta. This is not even a complete level.
Look at the screen for yourself. Would you say "hey! That looks like something I would like to play!"?
You need to actually create something, not just place random stuff in the editor. I see a guy holding a famas shooting a gasmasked dude with an ww2 submachine gun...for some reason is there a ladder type thing that looks completely implausible with a rifle on it. I can clearly see the end of the map where I can most likely fall down into sudden void and die. And for some reason are there trees. To cut it short: This doesn't make sense.
If you have a problem imagining levels or locations, feel free to look up some photos for reference...a lot of other artists do that too.
Please get familiar with the basics of the software and download the
community guide.
Here is another tutorial. Its about leveldesign.
And
this thread will also help you a lot.
