Cute, could use work
For your very first flash project, it was nice. Cute, simple concept and nice music. It definitely need some work, though. Have a couple more options, figure out how to make the music loop... Things like that. As of right now it feels like an online greeting card - which isn't necessarily a bad thing, just not exactly what Newgrounds is for.
Keep working at it. Like I said, if this really is your first flash, it's pretty good. You could have some potential.
