Kelvin, listened all the way through then skipped around a bit to relisten to a few parts. Nice minor blues! Your production sounds right for my listening environment, and you've made nice choices throughout. Nine Zero sounds appropriately cool, but I would like to hear a LITTLE more variety in his phrasing, especially as the song wraps up. I started off saying "I can't believe that's a vocaloid" then by the end I was saying "yep, that's a vocaloid". But I don't mean to detract from my overall thought that this is a very cool song, and I enjoyed my listen!

Too many guitars (is that a thing?)
