Revealing mistake: When River and Eden are talking in front of the kitchen window, every other camera shift alternates between different backgrounds - still/blurred versus clear/actively snowing. The props are also different. (00:14:15)
Revealing mistake: The position of the lamp (upright or tilted) to the left of the screen varies, and the way the light is cast on the wall above and below the lampshade is not realistic. For example, when the upper part of the lampshade is angled away from the headboard, the light projects below the lampshade shorter toward the left of the screen, not elongated. (00:01:00 - 00:03:00)
