A lot of the melodies crowd over one another and seems to have a severe lack of mixing, and in some cases the piece sound’s dissonant. The vocaloid also seems to not be well made, and many of the instruments are too high pitched, probably to make a “I’m going insane” atmosphere? Either way, this isn’t the best, but it’s definitely not the worse I’ve heard. The main problems are the volume, the mixing, and the key. Just keep practicing and experimenting, maybe look up a tutorial or 2 on how to do something better!
Your DEFINITELY gonna be scouted, in fact, you already are it seems, you might be mistaking scouted for “Whitelisted”, when that will happen, I have no clue, but you gotta be patient, it will come eventually!
In conclusion, keep practicing! Don’t let anyone’s review good or bad get the best of you, and learn from it! I look forward to seeing what you’ll become! :D
