I favorited you both here and on deviant art, because seriously, your stuff is simply amazing. =) The cute factor is overwhelming. They're also just really, really good drawings.
Pretty please fix the sound on the other animation you submitted here? (Which is awesome as well?) This one could use sound work too. No one likes to watch a silent flash.
The cupid flipping around, as someone already mentioned, was really goofy compared to the rest of the flash. And some parts could use aditional in-betweening.
I still really love this though. Please submit more, because now I know you have things hiding away on your other site. =3
