I think I've improved.

Here's a skin that isn't based off of the 1.14 loading screen graphic which I made some time ago but was too lazy to upload.

You might notice that this doesn't use the Alex model. This is because I recently noticed that the arms on said model are offset from the shoulders, creating a weird seam under the head. If only I found this sooner, so many of my skins would look better.

There's not much more to say. Enjoy.
