Continuity mistake: When Ariel is crying and Sebastian comes to comfort her, there's a vase, two planks and a small bottle behind her. When the angle changes, every object is different, even the area looks much wider.

Revealing mistake: When we first see Max, his paws are leaning on a balustrade and become transparent. Though it may seem like it's an optical effect because they're in the shadows, the next angle shows them fully lit and opaque.
