I can't really help you to become a great mapper. I can also post feedback and tips that
you can improve your maps. But you need to learn the basics by yourself. Try different things you're interested in and try to understand how it works more and more. As MyerRs already said, trying to copy parts of other maps might help you with this. You don't need to release all this testmaps, it's just for you and your learning process.
Now to the map. It's way too oversized. Too big, too much open area and too empty. Also the barrels are too wide and the small boxes are misaligned (scale down the surface size to 0.5x0.5). The grass ceiling looks unrealastic. The flame looks horrible with one brush (look at
_flametest.map).
And of course run a final compile without any errors, problems and warning to get full vis and lighting. Stop if it doesn't work and try to find a solution (

For now i won't upload the map to our beta server.
