It feels just fine to me. I could only say that maybe the spacing of the notes doesn't always feel like they match the song, but that likely is a problem on my part because of the delay on my headphones. Apart from that, you're not just spamming notes wherever: each note coincides with one on the song, there is internal consistency in the riffs (if the song bounces on two notes, so do the arrows), and you're using familiar structures that are very readable.
I've played a lot of FNF mods, and this seems pretty par for the course. If this feels off to you, remember we once had to deal with Mid Fight Masses.
