Interesting name, pretty nice and clear pick actually, I like it.
The screenshot reveals the map fair enough, but be sure to use the command hidehud to disable the hud shows up when making a screen (shortkey 5).
The map has been packaged excellent, which is great ^^.
Theme
The theme seems to be pretty clear, castle-ish. Pretty over-used but there aren't a lot of it like in this way.
Texturing
The texturing isn't bad, but could have some improvements. Using the WT_GK_002 texture in the gor folder next to the ik_brick_12864a texture of Iikka "Fingers" Keranen looks pretty odd (press F9 when you selected a surface, it will echo the path and name of the texture). Using the of Mitaman also isn't really fitting the castle-theme (that texture commonly fits better to urban or futuristic-themed maps).
So I would advice you to stick to 1 certain theme, instead of specifying several textures from different texture-packs. Nevertheless, seems to be a fine map config-file ^^.
Nice to see some texturing techniques as well, like the texture-blending at the lakes.
Geometry
The geometry seems to be pretty efficient, yet too efficient if you ask me. Everything piece of geometry is so minimised in detail, that it became sharp (like at the start of each hill and inside the lake). What about making it a bit smoother, for a more natural feeling?
The mountains are pretty fine, but I noticed there are still some geometric errors, like at the end of the lake and on the mountains itself.
Lighting
The lighting seems to be not bad, but it's not matching the skybox, as every angle of shadows are just the opposite of that they should be. Be sure to correct that by using yawsky or by repositioning the light-entity.
Detailing
There isn't a lot of detailing in the map. That's a shame actually, as there can be added plenty of that even just as mapmodels (like the axe or the shield). Keep in mind, details can make the difference between themes also.
Clipping/Noclipping
The clipping isn't logical and also contains several errors.
Flow
Because of the clipping, there actually isn't any flow.
Gameplay
It's not a bad thought to create a map which makes you can sniper (I would rather call it "camp" though), but keep in mind that's not where Capture The Flag is designed for. As the mode is saying so, players should be able to capture the flag of the opponent and bring it back to their flag. In this case, it's impossible to do so, which actually kills the mode. So that shouldn't be done, else the mode would be about fragging, not about scoring.
Next to that it's also pretty boring, as it feels like you're in a cage shooting other people from a distance, which are also trapped in a cage (so you could actually also call this map cage2cage or cage_fight =P).
That's why I would advice you to delete all the clip on the balconies, so players aren't bumping against an invisible wall when they try to get off the castle. If you've done that, just add a ceiling of clip on top of the mountains and add some variety in pickups as well, because players could better play instactf now, then just classic ctf (so you actually killed 1 mode twice, with just 1 try).
I wouldn't mind this time, but the map actually should be playable in other modes as well.
Overall
The map isn't awful or something similar, but still not feeling great (despite some things which pleases me to see). I'll rate 4/10 for now.
