Video game music compositions

[Hyokune]

Hello this is my first post here!
To shortly introduce myself, I am a Korean university student studying computer science in New Zealand but hoping to become a musician either working in the game industry or Japanese music area.
I was able to compose in highschool because of the fact that I have been a pianist for nearly my entire life.
I am pretty new to DAWs and mixing etc. so I do no have that great variety of equipment to work with.

I was wondering if I could get some serious feedback of my original songs for games.
Mainly this song: https://www.youtube.com/watch?v=7Mw1U9xLiOI

Few other examples are in my soundcloud: https://soundcloud.com/hyokune
