Here's some music that I've made after finishing my digital music course

I'm also wondering what genre my music exactly fits into? It's very videogame-y but that's too broad, and although I've tagged them with Drum & Bass I'm not sure that quite fits.

March Of An Unknown Entity!

An Ocean Of Gateways

Quand And Ale

River Of Stars

AN ESCAPE FROM HELL

Edit: Just to add, constructive criticism is welcome, I'm still very new and looking to improve
