On I; This edge is blurred when it shouldn't be. It should be more in focus, because it adds depth when it shouldn't be there.
On II; This bit is a little too blurred, because the top isn't blurred as much, so it kind of sticks out.
On III; The same as II. It's too blurred and doesn't blend with everything else.
On IIII; This edge is half blurred and half in focus. Wat.
On IIIII; This blurred part leads to IIII which isn't blurred. Again, wat?
