Nice one stefan :D you have long way though, you need to fix your structure, and produce more and more, try to create melodies and practice by replicating other songs. The issues to this song were obviously many but i can't be very specific as you are new to music
In very general words, you need to fix those
-Song Structure (Try something like INTRO, MAIN PART, BREAK DOWN, MAIN PART, OUTRO)
-Song is very repetitive, add new chords/synths/melodies etc
-Song needs better automations, in some parts the resonance filter is very loud you need to invert the Frequency with the Resonance, it's a nice trick and if Frequency is 100 then resonance should be 0, if freq = 30 then res = 70 etc...
-You need to learn mastering your songs, in other words, balancing all the audio for a better sound, we usually do this by adding a limiter on the master filter, compressors on each instrument, and reduce the volume in order to fit every melody and not make it loud, the beat should mostly louder than the melodies, etc so basically CLEAN UP
I hope you will understand my tips as your english is not good xD but you will learn lots of stuff just keep making songs
