Yeah, I know I'm late, but I finally got around to download the model and chex0r it out
Except for one minor detail and one huge problem the model really, really is amazing. It's absolutely beautiful the way you worked in all the pwetty detail. And you're the first person to my knowledge to get the cockpit to work correctly, which is another bonus
For the model itself, I would've preferred if the little pipes on the engine pods (in the recessed part) wouldn't be modelled in, but only textured. It's a bit of a waste of polies and it would look more detailed(!) if it'd be textured in. However, that's only the minor problem.
The rather unpleasant thing is the textures. It is unclear to me why you preferred to go with a completely new UVmapping when the original one did a rather good job. On your last version of the hi-poly Herc it was almost perfect already (save the few stretching issues), so why throw it overboard and go with a worse UVmap? This is the only real problem with this model. I can see why you added the second (cockpit) texture thingy, and that's fine, but changing the base texture IMHO wasn't a very good idea.
