Looks quite pretty, some old skool techniques i see in there from classic DM mapping style, which doesn't seem to impact that negatively on the TF2 style. Although the lorry crate surrounded by grating on the floor bugs me somewhat.
There seems to be a lack of ammo, don't forget your engineer will want more than 1 or 2 spots around the intel to set up. especially between nomans land and the intel room (essentially the courtyard).
