Some small copyrights issues
This might be a little dumb, but last Friday I uploaded a concert band arrangement of the Main Theme from Beetlejuice. Everything went well, until today I noticed that a company called "Alfred Publishing" made a copyright claim on my score, even if I arranged it completely by ear and was relatively original (with the main structure of the piece I heard from the Youtube video being used and the having changed the key). I quickly deleted it to avoid further issues and I still have it in my computer. The Community Guidelines mention that I should not upload copyrighted material publicly. I just wanted to ask if I still risk being given a copyright fee or anything related, thank you.
