Music Confirming Originality

Hey guys so there are many times when people make a really great song only to find out it is just like another great song... that was copyrighted. Not sure about the rights for the songs of Wynncraft, but either way I respect what Wynncraft has made. I'm composing some music for my friend's project, and I'm using Minecraft Noteblock Studio to compose and playback music. These kind of sound like they could fit into Wynncraft so I want to check that they don't happen to actually be just like a song or 2 from Wynncraft.

Here are the 2 basic melodies I've made that I will eventually transpose into Orchestral sheet music once I develop them more.




Thanks for any help that can be given! :D
