First of all, welcome to the site
When looking at your map, I'd say that the entire thing makes no sense.
Why would you have 3 big concrete pillars in the middle of nowhere, and then connect them with bridges?
The layout is basically one airborne road to a point with very little cover.
It will either be a sniperfest, or a race about who can get over and camp the other spawn the fastest.
I know that you are new to hammer and stuff, and I salute you for taking a crack at it (Can always need more people to produce, rather than consume only

), but we kinda want to keep the workshop for more serious projects (Tho some recent additions might seem to contradict this).
I'd suggest you to read up on some design theory. There are lots of good tutorials, and theoretic writings on what makes a good level - Things like multiple routes, short sightlines and height variance - And then get cracking with a real tf2map! Its not quite as unmanageable as it might sound actually
As you progress towards your first testable alpha, you can get feedback along the way by posting screenshots in our
WIP thread, which is the most popular thread on the forum.
Once you have a playable test version of your first map, we can test it during a gameday event. You'll just have to sign it up accordingly (You will find gameday announcements in the
events subforum)
Good luck with it
