But on the bright side I could recommend a few things looking at the snapshots, take these as you may:
-The clouds could be changed to low poly meshes combined with the 2d func_illusion.
-The Actual Columbia is very dynamic, with platforms bobbing up and down due to the change in airflow (In reality they're just atoms suspended in mid air with the help of balloons to stabilize structures), but one thing you could do is make the clouds on the bottom move a few units up and down, to simulate the effect of floating. You could also add rotating windmills or spheres with balloon textures
-Adding more buildings to the skybox give the presence of more of a city, maybe add a few RED blimps in the distance to give more of a "RED" vibe to it. Also add planes and AA guns / batteries to give the appearance of a sky fortress (Which is what Columbia is supposed to be).
-Add stuff that isn't in Bioshock Infinite to help build off the TF2 aesthetic. Because it's not the actual Columbia (It's an alternate universe version), maybe adding stuff that isn't in the actual game would help make it a little more unique?
-Alternate skybox with fields at the bottom / mountains / other tf2 maps.
I can't really play this, but I have judged based off of the screenshots. Gameplay wise, you could add floating buildings that jumpers could land on.
