Obviously I'm biased, being partial to your TL, and not knowledgeable at all on the period you're in right now, but I think I can make a few relevant comments:
I like the fact that you've divided it up into smaller sections; it makes it much more enjoyable to read. You may also consider putting a brief (1 or 2 sentence) gloss at the beginning to let people know of any divergences from OTL in each span; it will help get the discussion rolling. Otherwise, people will read, but unless they know the TL as well as you do, they won't be able to comment. You've got a lot of subtle changes that someone who isn't familiar with each period may not note at first.
You might also consider dividing up each year or section of a year into a broad geographic area; that way people can "zoom in" to their area of expertise and offer comments or criticism more easily. Preferably these section divisions should be set off from the text and maybe even bolded to make them more eye catching.
I think some visuals will help. People here build entire TLs off of maps. They respond well to them. There are a couple of people here who are very skilled at map making, but I think that they'll need to work closely with you to make sure that they catch all the important details, of which you have a super-abundance.
