What can I say? I just did what mojang did back then, they made a mob and gave it a texture they already had which were oak leaves, so I did the same thing but with modern leaves and uploaded it on reddit. After seeing some people liked it I uploaded it here.

For reddit I just needed the front and I accidentally left the back flat colour so for release I fixed it.

Feel free to put it in your own texture pack mashup, etc. I don't mind.
