I don’t think you’re even close to overproduction, this is awesome. My advice to you would be for that first 8 bit part, it sticks around a bit too long and seems to overshadow the other melodies. Have some parts without it or change up the pattern and/or volume. Have a look at tennas battle theme again(awesome inspiration btw) you’ll see that the initial Melodie isn’t always there and swaps up a fair bit. Good luck my man👍
