use your 2nd texture layer for detail texture
use your 3rd texture layer for a macro texture
use your 4th texture layer as a lighting adjustment layer
the biggest problem I see is the lighting on the texture
doesn't match ( to dark) the environment.
the detail texture is great for adding detail to a smaller texture scaled over a large surface. the macro breaks up the redundancy or pattern in the tiled texture and gives detail
from a distance. I take it the submarine is the main
object in your game so you can get away with applying the
textures to the object. I wouldn't apply multiple textures
to all the objects in your game unless you can afford the
performance hit.
if you have unreal tournament you can see these in action

you can also disable detail and macro textures in the game to see how really ugly the world looks without them.
