Anniversary gift

Hi, I have another wip to share. My anniversary is coming this weekend and i have no money to buy gift so I am trying to make something on blender for her. I think I am going to change this so all the hearts come from aproxamately the center and just pile up and then overflow, but this was the first test render to get an idea of how it will look. Also, does anyone know how to make the hearts stop twitching at the end?
