Nice try.
But this isn't the type of thing Newgrounds is for.
Besides using a majorly overdone meme for the basis for your flash, you didn't really contribute much to this as a whole.
Your star background is primitive at best, and it could have used a few more animation frames. The same could be said for your rainbow.
Overall your choice of another author's remix of the Nyan cat theme was the only discernable value I can identify from this flash.
Next time try and come up with your own flash basis instead of an annoying meme that loops constantly.
You have potential, use it.
