Extremely well done!
Artistically wise, I love your style, and even though the animation wasn't very smooth, it didn't need to! The animation simply added to the mood, thus creating this rather slow-motioned dimension, which can be a state of our mind. The artwork was simply beautiful.
As for the meaning, when artists usually don't state the meaning of their art, we have the freedom to find one of our own. Not opposing myself to StayBeautiful really, being unfocused simply opens more doors. But I'm not saying that StayBeautiful has no point - since if you really want to pass your message, you'll have to state it clearly... But oh well.
You did a fantastic job, keep it up!
