There is a scene where Krunk (sp?) bursts into the tent that Yzma's sleeping in. You can see her wig and false eye lashes on stands. Perhaps she changes the number of eye lashes depending on the outfit she's wearing.
Was it the same angle? Because it could have been that when you look on the side you see three, and then when you look straight you see 4 or 5. Besides, who would really notice that and care about it besides you????
Hey, don't let the others get you down. The first time I watched this movie, the eyelash mistake caught my immediate attention and drove me insane throughout the entire movie. I saw it too, don't worry! It wasn't the camera angle, it is very clear that the eyelashes change constantly, even when wearing the same outfit. I believe it is due to several different people doing clean up animation, but that's just my thoughts on it.
