As I see, over the help forums, they also tried - just the file size did not turn out. First of all, purge everything not used in the file. Go to window > model info > statistics and at the bottom... If this is not enough, best is to start with image textures. Make sure that if you used photos as textures, right click on the face and make texture unique.
