There is nothing wrong with #1, 2, and 4. #1 and 2 are perspective changes. The picture is on the other side of the pencil cup, and he flips the menu over in the second one. The third is not an eye color change so much as a light change, that ANY real artist would recognize (black and white vs. gold and blue)
In the Lion King, in 2 different scenes, Nala has a different eye color. When he is talking with Simba her eyes are blue. However, when she was about to attack Pumbaa her eyes were green. In the rest of the movie, her eyes are green.
