NameMC Trending Skins - For skins more up to date with Instagram fashion / Young Adult fashion PlanetMinecraft - Very talented skin creators (very unique skins) Skindex - (IMO) A lot more simplistic skins
A few of my skins I designed, I made a serial killer one with a skull mask.. that was my Halloween skin :P. But the skin I have on now is a reflection of what I look like, its still a work in progress I have to edit the shading.
I had one of my good friends that I don't even talk to anymore for some reason made my skin for me, she just offered and made it without me even knowing so I accepted it because it was awesome and it was made by a friend.
