Well, you didn't say it was your first map but I have the feeling it is. The grass texture you used is an HL2 texture, and should be avoided for TF2. When searching for textures to use in a TF2 map use the keyword 'TF'. Your buildings are also made of dirt, which usually isn't a good thing
. The skybox you have set is an HL2 Skybox texture, to change the one displayed go to Map->Map Properties and select the 'SkyBox Texture Name' Field. The list of TF2 skyboxes is
here. Also your map has been compiled in fullbright, which happens when Hammer detects no light_environment entity in your map, so just add one of those and some 'light' entities around your map in the buildings and you should be good. The map also looks a little too open for a TF2 style of play, snipers would dominate. I'd suggest maybe looking around the
TF2 Valve Developer Community to learn a bit more about mapping, and then spruce the map up. Also basing a map off of an orange map is generally not a good idea, as they aren't very well designed. And one final thing, your HUD looks a little funky, especially since there's only one CP in your map. Try deleting any that you left behind in your map before compiling. Also don't set the 'Cap Layout' field in your team_control_point_master entity. Hope that helps!
