I've updated my skin on the Minecraft website and the MultiMC 5 client I use is displaying it properly, except the Ears Skin Manipulator website won't display my new skin when I open the game through the in-game link. Skin, Loaders, and Mods provided below.

Nevermind, I found out that that issue I was having was missing the magic pixels in my skin, added them back in and it's all working now.

There should really be a picture of the magic pixels on the website so people know what they look like compared to the parts that are actually used in the skin.
