Here is a couple of pictures including close ups of the pulley system with rope attatched. I had to edit the system slightly as it wouldnt work how it was before but in theory it should work now if it was real. In the close up image i have applied an Ambient Occlusion to see how much of a difference it will make in render time and the answer is... a lot. Any way here they are, it has made a nice difference though especially in adding in depth and shading.
The first of each is both images compiled together, the second ones are the ambient occlusion and the last a normal render.
