The details look nice but i dont know how well it will play.
if u look at Valves standard maps the control points are usually placed into a corner. and if they are, they have many entrances to them. also think about where can engies place sentrys to protect the point? make sure they have a destroyable/fault in the placement so Blue can destroy them. where can snipers sit and snipe? (no dur

). can pyros ambush? (that goes for the whole map) do soliders and demos (more soliders) have a good area where they have a height advantage?... do spys have good "hiding spots" to recharge their cloak?
and what type of CP mode is that? is it fight for the neutral one then push threw the team ones? or what?...
also if the point u are detailing is the final point for that team try and make it look really that teams area. so if its blu's area make it sharp buildings and blue textures. maybe behind the point so it looks like the area goes further into the map not just stopping abruptly
just some things to think about
