I’ve been told to add lyrics, which is its own issue to do in Japanese alone having to sing it. I’ve also been told the first two sound like Christmas when i was going for space. I can not make chords for the life of me. I had to copy some for the third one. I also can not do base, it just doesn’t work out to well for me.

Anyway I need opinions and improvements possibly. all of these were made within 3 days (each on its separate days).
