My old model is on an external drive, but just looking at the new download, I don't see any difference. The instructional build photos are the same ones from earlier. I printed the page to pdf when I built mine, and the build photos are the same.
It is a very satisfying build. I encourage anyone to build it. My son loves the fact that it has wheels that roll and has those little fiddly details that make it a beautiful model. The instructions are excellent, so don't let that 'fiddly' remark discourage you.
