your UTAU has a lovely, low, mellow voice, as you've showcased in the cover above. being a scrub, myself, i'd greatly appreciate some sort of romaji alias, if you've got the time.
if you ever decide you're up to it, shoot me a PM or something! i'm really fond of this sort of voice, there's a lot of applications outside of the same "general j-pop shoujo vocaloid song."
and it really does sound beautiful.
