It's when you have a great figure, and then you discover a tiny thing thay always bugs your when you look at that figure.
I have a few figures where this happend. Topside is one of them, nice figure, but his yellow demon eyes bugs me. Blaster is another. If you look at his bare piece of arm, you'll see that it has wrinkles. So either he has some very blobby arms, or a flesh coloured shirt.
Has this ever happend to you? Is there any tiny details that bug you?
