This is some pretty solid basis, and you can work on a lot of things to make your vision truly shine : first thing is the writting, some melodies fall a little flat and some arrangements got me a little "interrogative" about the intention.
Forgotten cave for exemple doesn't feel like a boss theme, the melody isn't strong enough to carry the thing by herself and the repetitive, unpercusive arrangement doesn't compensate that.
About mixing, the drums in Forgotten sky are nice in term of writting, but they do feel like they are from another time (the 2000 in a garage precisely), so you can work on mix and processing to make your world come to life.
A nice submission with a lot of potential, can't wait to see your progress next year !
