I tried to comply with the OMR too... I'll check the differences when I can 
OK, so you've defined the different submodels in a "logical" way, to allow easier rotation/translation when needed (especially for movement or animations), whereas I just followed the instructions. Your way is more practical indeed, but is it preferred?
I may also note that at least my editor (LDCad) shows some very small overlap in the cockpit's top cover (I had to rotate it 43.9 degrees instead of 44, if I'm not mistaken), and some gaps between the minifigs' hands and arms (you could use the minifig I posted in http://forums.ldraw.org/showthread.php?t...02#pid7102).
