Fr 8-bit, doesn't sound bad. Use less loops that are not in the same Key signature. Key signature refers to only specific notes that can be played in a song. There are 15 different key signatures in total. If a note, sound, pitch doesn't sound right, its likely not in the same key signature as the rest of the song. This concept is music theory which is a pain to learn, but it helps make your music better. This is good, but the main melody (Loop) is a bit loud, Automation would fix this or effects (Reverb, Filter, EQ, etc...) I hope this helps, its up to you on how you perceive music!
I feeling like I'm playing an 8-bit game.
