As Rory begins to drag the sleeping Amy up the stairs of their cottage, the picture on one wall is wonky, as if it had been knocked. In the next shot, from behind Rory, the picture is straight.
When Rory winds the generator that the Doctor gives him, Rory is holding it straight up, and the arms of the device are not moving. When the camera angle changes, Rory is holding the device pointing upward, and the arms of the device are flapping.
When Amy makes the ponchos, she cuts a slit in three blankets. When she puts her poncho on, the slit is across her, not down her like the other two. When the shot changes and she goes to stand with the other two, the slit is suddenly going down her instead.
At 6:39, the outside of the TARDIS set can be seen. This includes items such as a light and the wood framing for the upper level.
