First of all,I think you forgot a C on your .bsp save (when you download it you get "tf_tpm_a02.bsp". xD)
The map,for now,MIGHT be a little bit underscaled. The briefcases might be way too close to each other,leading to a very short gameplay.
If that "loading dock" can fix this problem,sure. Go ahead.
One thing I noticed... Are you trying to make a symmetrical map? Because for now,it doesn't look like it. Usually half the map is the mirror of the other half. There's a couple of """"mistakes"""" (Yes,I know,this is an ultra-alpha,but I want to point them out anyway.)
Shouldn't be this "Lunch counter" on the RED side too? If not,BLU might get a pretty small advantage,and that might be bad. We want a pretty balanced map/gameplay. A team shouldn't be better than the other with a simple "building" the other team doesn't have.
Same in here. Why does blu have less "windows" than red? It might be pointless (again),but it might give more advantage... again. xd
And maybe raise this roof a little bit? At least for the scouts to move with more freedom when they're on the boxes.
So yeah,like you/I/we/the whole universe said: It's a big ultra-alpha. Yet it looks promising.
I really can't wait to test it out. ;D
