Nice video overall, the beginning is a bit too fast for the song but then you found your rythm and it fits better.
You added some nice fx, like the heart background or the brush overlay thing (dunno how to really call that) but try to use them more wisely and not all the time xD, and sometimes the brush thing is saturating so be carefull on that. But it's nice that you tried to stand out from the usual romance videos, hopefully you'll get rewarded for that
Good luck for the ranking !
