What do I need to do to make a Minecraft mod logo follow the rules? (non-data URL images)

Could a moderator help me? What I need help with is that the moderator who rejected my Better Minecraft mod gave a vague description. Here's what they said:

Please improve your mod picture. Make sure it's is your own work that represents your mod and that it follows our publishing guidelines. You can read more about mod page rules and terms on this page: https://mcreator.net/wiki/modification-publishing-guidelines Thank you for understanding!

Minecraft logo is also protected by copyright laws.

I don't know what I need to do to make my logo be valid.
