I'm not sure how the note system works so I'll point out a few things here.

I really like where you're going with this paper. The simplistic theme is great, and you've done a great job with directing the viewer through the wall.

One suggestion I missed with the notes relates to the lyrics: while I like how you have them in the wall as small and linear, the positioning is so that it looks like she's sitting on the words. I'm not sure if it was intentional but It seems a little odd to me. I was thinking they could be moved up just a bit behind her.

To add to the given suggestions, maybe you could replace the lines in the musical notes with the lyrics themselves, remove two of the upper lines along with the notes on them so the top of the wall wouldn't look too occupied compared to the bottom, then add bubbles down to the bottom of the wall so it won't look too empty
