Some general stuff:
- The map doesn't have a consistent theme to it. Every corner you turn, it has a different texture set. It doesn't feel like a location - just feels like a bunch of textures thrown together in a way that doesn't makes sense -- grass and water in one area, snow and ice in another, and all sorts of different rock types that you wouldn't see adjacent to each other in reality.
- There is more than one water plane visible, which causes issues/poor performance with reflective water.
- The lighting isn't right. Everything is fairly uniformly lit with some discolored/overbrightened reflective lighting. You probably need to set appropriate sun lighting angles and use the .wal and palette files from the BSP pack.
- The flags on the pillars will be problematic if I ever add UI elements to help people locate flags in maps. I would take those out and just make some nicer looking pillars instead of a gigantic block of wood.
- The map feels kind of awkward to navigate. You constantly have to worry about falling into the water in the base area, and some of the paths have abrupt angles that don't flow well.
