Pity
I listened to some of your other stuff, to be deadly honest your stuff isn't amazing but I know how you feel because I'm pretty much where you are. Probably because I made most of my stuff with Musescore. I think what you lack is diversity and you have too much cheesy sounds like the (kick,kick,kick,crash), Only amazing artists get away with that.
listen to some other peoples songs that sound more within your range of skill. Trying to be like F-777 is too crazy, maybe listen to halcyonic falcon X which is less crazy: regular chord progressions and simple melodies but still sound effetive.
Don't be so harsh on yourself just work on something and if it doesn't sound good to you then it won't to others you have to keep working until it does sound good to you. Go to this link: http://www.youtube.com/user/SuperXav1 er#p/a/u/0/5HGe-EKW1kc
It is my most recent song, realise that it is just one chord progression throughout the whole song nothing complicated. Hope this helped you to get better.
P.S. Your Question: "What's Hardstyle?"
Answer: "It's the sort of techno/trance songs that people would shuffle/dance to."
