Hey, your mod looks cool, but I wanted to tell you, that the GPL 3.0 is not a valid license for minecraft mods.
A short explanation can be found in this modrinth blog post.
You might want to consider to change it.

Thank you for bringing this to my attention

For the record, the mod is under the CC BY-NC 4.0 license. That license matches my intent anyway so thank you again for pointing out the issur.
