unfortunately accounts made after 2017 can't have their songs in geometry dash for some reason. (I think it had something to do with too many people creating accounts just to upload some song they didn't create and then someone would scout them anyway.)
Anyway, as far as this piece goes, it sounds good, but so many piano versions of this song exist that it is really hard to confirm whether this is original too. To be honest, I think it is original but like the other guy said, make a few more.
Edit: yeah I know you didn't make bad apple but I mean I also don't know if you made this piano version or just found it. And then the question is whether or not you played it by hand if you did only find it.
