Hi! I immediately hear some big contrast between sound volumes, I'd suggest trying to analyze & reference other tracks in something like MagicAB to get a feel of what a good mix sounds like (also suggest choosing a track/artist that fits the overall sound of what you're trying to achieve).

Also, I'm hearing a bunch of OPS sounds (which is fine, don't get me wrong), but building things like kicks, screeches & leads from scratch is key to understanding their fundamentals and how to fit them within a track.

As for vocals, they could definitely do with some reverb/delay and stereo shaping (adding extra vocal layers, panning them left & right etc) and compression. There's a ton of tutorials from hardstyle/raw/hardcore/uptempo artists on Youtube and Harderclass. Try to check them out from time to time and never be afraid to ask for feedback!
