I just feel joy at the models. I think it's the sentimentality of having seen such an inside glimpse of the Nostromo crew when they were in the hayday of commenting in that AXP thread.
EDIT:
Just to add to this, I love art. I understand the skill and patience that CG takes, and it's something I could never do so I respect the hell out of CG artists.
BUT, there's just something about the models, knowing that a person's hands were dirty with glue and paint and they put elbow grease into perfecting something. I just prefer that.
