I like your intro, but I think the song itself coming in too fast. though it would need a better structure 0-34 secunder you type a basic harmony of the song then explodes into full song hardstyle. It's sort of a little "oh what's happening here."
I have favorite hardstyle artists like Dj Coone very good insperation.
Then you can always discuss how long the song should be, for me it is not important as long as it caught the ear of the song that it is always something happening. I listened to 4min + and it became repetitive, adding piano, another synth does not help. I simply think you built the song without having any planning how it should be but you just drove on. A good foundation for me is an intro> Break a verse>, chours and a crazy buildup> Main build. > Breakdown> build up again> an outro. but there are of course different ways to build on but personally a song must follow a red line and it does not end here.
People say it's part of the art. The music is an art.
Otherwise, I think it was a good song the only thing that you need is just some insperation.
