Alright look how the circle surrounding his pupil gets broken up into two, possibly three spots. Those COULD be the sharingan dots.

At the bottom left there is a gap in the circle around his pupil. Towards the bottom right there is also another gap. I expect a gap is in the top right which is covered by his eye-lid.

I know it's a long shot, but this could be Obito. They zoomed in on the eye so people with an eye for detail can catch this stuff.

Even if you think he gave Kakashi his eye, the eye shown here would be the other one, leaving them both with one Sharingan?

Ok bring it on, tell me how that is just an artistic error..but is it really?
