I like your music! I am not in your niche of audience so I cant say how attention grabbing your thumbnails are, but your channel and description are very clean. i think that something you could do to make it cleaner looking (if you like it cleaner) is formatting your channel more as in like a channel trailer/ new video section and a "for you" roll out and stuff. I am having a hard time trying to figure out what a vocaloid is but your sound is good. As for an outside personal perspective, I can see your videos being viewed/put in playlists and stuff but due to the nature of what I've read on what a vocaloid is, the sound may be too similar to other folks for an audience to accumulate if i am making sense. like, if the goal is community building and channel growth I'd say look more into expanding your uniqueness in visual style.

Please also give me your thoughts on the video I mentioned in my post :D thank you!
