Minecraft Skin not 3D?

My Minecraft skin is not displayed in 3D and therefore looks really stupid D; , The head looks the worst, which in my current skin is the only thing that is not 3D. Can you help me to get the skin / head 3D? I've already tried Nova Skin to edit, where the skin synonymous normal and 3D is displayed.

Image?

Sorry, I found the answer. It was because I was not wearing the hats in the Skine settings, which meant that the highlighted details were not displayed.
