The master is a bit weak and things need to be louder, either things were quiet or things were smashed by your limiter, but things need to be a bit louder. if you look at your waveform you can see that it is really small and thin, compare that to other peoples' and you will visually see the volume difference.
I can tell that you are new to producing as things maybe aren't as big as they could, even though this is techno and the contest is future bass I'll still give you feedback. More layers are needed to think your mix. So maybe some more bass layers or lead layers and so on. Some ambient ant atmospheric sounds would do well as well.
