I would space the "V" and "A" out a bit. The other two have nice amounts of kerning, but those two are too close and present two different styles that don't sit well with each other. If everrything was like that for "NOVA" then it would work. You can have the Sun with more kerning, but you would need another letter (which "nova" doesn't permit) to be with the "N" so that it would sit well and that line of copy would work. But thats not the case.
