The layout is not bad, but part of the layout have to be intended to an aesthetic aspect, the layout doesnt have to be just playable, it also has to be sightly. Forge for example is an ugly map for my taste, very playable, but aesthetically is okay, the textures are a bit spamed, but the layout is consistent, the space used in every part of the map is calculated, is something wich i dont find in this map, where there are some small parts, and other big. The hole in the middle does not work for any purpose, nobody is going to go there, there is nothing really important, or strategic in that hole, the only thing you can do is to change to the other side of the map, that is completly unnecesary, considering that you will run more distance that you want, also, i played in this map some days ago, and i didnt liked that hole; it was annoying when i was going to the middle.
The boxes are the resource when a mapper dont have any ideas, there are other things that you can make instead of boxes, like terrain, or just more layout, the boxes in the bases can be replaced for some layout, some proper ladders, adjusting them with the entrance that is near of it.
in general the gameplay of this map is very nice, but not for insta CTF, the corridors are a bit long and also some parts are open, it is a very good map for effic CTF, it gives the enough space for combat and for recovering the flag, but in the appearance it lacks of details, and has very few textures.
The map is playable, but not nice in the appearance.
