Well, now I know that you're not supposed to try to cram excessive amounts of detail from the original source into Minecraft Skins. You'd think I would've already known that, but nope, haha!
This is Snake as he appears in Smash Ultimate. The two reference pictures I used are here:

I know that last one is a bit questionable but I wasn't about to use that meme of his butt as a reference for the back of the skin.
Maybe I'll get around to improving this skin, and learn how to make it look natural w/o the noise tool, lol
