Imperial Star Destroyer - Texturing

I have done my texturing for my star destroyer model, it is only very basic unfortunately due to me only using basic Lambert materials. I was going to find a texture to add in via projection/UV mapping but this proved to be very difficult to get right due to the amount of faces on the model as well as the more complex parts such as the engine bays and the hangar. Despite this however I feel that it looks alright in its current form and i am happy to use it for my final animation.
