It's not bad, I just feel that you kind of changed the tone way to much. The melodies differ in pitch and stuff. I'm not saying not to change the melody from time to time but consistency is essential for plenty of genres. The first melody was nice then it changed. Why was the second melody so quiet? Then the third one matched the second melody (the electronic part) then the growls were alright. then the melody CHANGED AGAIN. It was cool that time around but I don't know if you had trouble classifying this track. But I would set it to experimental. Keep it up, get inspired from others. You'll get there!
I hope you are not sleeping by this point. I sound like a teacher don't I. The short form I guess would be that even I need to learn plenty of skills. Everyone can improve, even pros. GOOD LUCK
