I love seeing improvement on your composition skills!
See, it gets a lot easier to make good melodies once you've start getting used to a piano roll. :))
---If you wanna learn about melodic notes, which can pop out melodies even more and make people go "OH MY GOD!" message me because those are always great things to use in melodies and should be used! :)
An example of a melodic melody is YOHIO-Without Wings an orchestra piece using a Japanese composition system.
