Why would there be a minecraft "anime".
Also, its better to say "cartoon", because unless your a Japanese cartoon artist, its not anime. I know the style that "anime" is parried up with, all most everything from gelbooru is considered "anime-ish" or something similar to the common anime/manga style.
Its best to say cartoon or comic at first
If you want to create a story related around minecraft, the best way to do it is through a few animations on flash or with a comic. Most people have made comic series dedicated to Minecraft already; if I can find one of them I'll show.
I do ask though, if you are making a "minecraft anime", I would like to see some artistic skill, some animation skill, some voice work, or some past leadership work of successful projects.
