The sphere that Archer and Trip land the shuttle pod on is supposedly the size of small moon, yet when they are on the sphere's surface, the horizon looks as if it's only a few hundred feet away. On a body that size with perfect visibility, the horizon should be miles away. Since the entire background is computer-generated imagery, there's no reason for this glaring mistake.
Hoshi's choice of attire while on this mission was impractical considering she was supposed to "stay on [her] toes."
