my first submitted model was rejected but i don't understand why it was rejected

[alccoder on scratch]

my first submitted model was a model called "infinity creeper" It was a custom Lego Minecraft figure model based on my custom Minifigure with the same name, I submitted it to Minecraft customs bc it was a custom model, but it got rejected bc it was a "fan-made" model. um, how!? It makes no sense how it would be rejected in the "Minecraft customs" in the custom/edited section of the models resource. It's just a modified version of a Lego Minecraft creeper Minifigure, can someone plz help me and tell me why it was rejected? I don't understand at all.
