Continuity mistake: In the scene where Raphael stops to listen while carrying a KO'd April through sewer tunnels, her position in Raph's arms reverses between shots. Furthermore, April is obviously played by a doll in this scene, since her limbs jiggle quite unnaturally when Raph moves.
Suggested correction: I don't see any reverse in position throughout the sequence; her legs are towards his left, her head towards his right, consistently. I am not sure about the unnatural jiggle part either, because I don't see much of it.

Character mistake: When Raphael is chasing Casey Jones after their fight he vaults over a taxi hood, never takes his eyes off Casey, but he somehow loses him.
Rob245Suggested correction: 2 things are happening; a shell backed stocky Raphael is chasing a lighter human athlete Casey. Casey has freedom of movement, whereas Raphael can't stray much from the shadows in hiding. :-) A knocked out Casey wouldn't be helping the Turtles out of the next evening with that memorable entry so I'm glad Raph lost the chase.
