it has some materials issues, like there is a big water gap in the port, the clip on the seabottom isnt straight but going up and down on a pretty wacky way (what about making the clip just 1 level and the water just 1 level? both still separate of course).
you can get stuck at the left side of the cave entrance to the YA, when you try to reach it by using a jump.
theres are some texture mistakes in a hole with a ladder trough it, close to the quaddamage (look at the quaddamage when you are at the hole. its just next to the ladder under a window).
another texture mistake is at the windows with those steel bars in it, close to but under the quadddamge (look above the windows. there has been used 3 different textures in 1 bar that isnt very fitting each other).
another texture mistake is in the upper house between the plank to the red base and the quadamage ("rocky" ceiling, while the rest is just that white stonish texture).
im sure this map is not designed to play assasin on :P.
further, the map looks great and plays nice too! you see enough to run and frag and it creates a less campy port ^^ (wich is great!).
nice map, just fix those small points! 9/10.
