I really like the instrumentation and the cosmic mood. Great opening.
Very nice melody that the vocaloid presents well.
You should definitely continue with this song. Hearing the female voice, I think this should stay with a female singer because it just seems to fit the whole mood and tone of the song.
Thanks Ezekiel's Storm for your kind comment

Cosmic mood - I was aiming for that, glad to hear I succeeded

Yes I agree, this was made for a female vocalist and it fits the mood and the genre (like, for example, Cocteau Twins).
