I've just watched part 1 on YT. Great quality, and fantastic sounds. As said before, the only negatives are the obvious roll=over setups and whatnot, but these are limitations of LFS, so its nothing major.
My own personal negative, would be that in some scenes with the XRG, it sometimes has the older 7 spoke wheels, and then in the next shot, it has the newer multispoke wheels. Like at the beginning in the carpark for example. Nothing major, but something i noticed.
All in all, a great movie*. Well done.
*= So far. Im waiting for part 2 to come up on YT.
Its in HD now btw.
