Yeah, I caught the vent detail issue, but the 'bunching up on tauntaun' problem hadn't occurred to me.
I have a sewing machine here, so I'll make the alteration if SS doesn't, though it would be tricky.
I think I might actually contact them and mention it, hoping it's not too late for them to make the correction.
It's not due until November SS... come on.
Thanks for the heads-up, Misterscruff.

UPDATE: I just called SS and spoke to Jennifer, who I have spoken to a hundred times- really great person.
I explained the issue in detail, she looked at the photos posted on their website, and she promised absolutely to bring it to the attention of the design team.
She agreed the jacket might look odd and bunched-up at the waist while Solo is mounted on the tauntaun.
I told her that I have a sewing machine and could try to alter it myself, but she pointed out that I wouldn't be able to fold and sew a proper hem on both edges of the flaps without creating a gap in the middle- and she's right.
She also warned me that the current version, with all it's details, has been "signed off" by Lucasfilms, contractually obligating SS to produce the design as it exists now. Any further changes will require that the final version be approved and signed-off again by Lucasfilms. She seemed optimistic though, given the fact that there is still plenty of time before release.
I told her to have the design team look at the scene in the film where Han Solo is shooting at the probe droid for reference, and she actually wrote that down in her notes. Thanks Jennifer!
