I started to do a rotating heart, but I went with more of a beating heart with some color change on this one as I was progressing through, it felt more like what I was looking for in this. I will likely do another and may even use this one in a project I am working on. I added a black outline and some highlight on the heart to make it pop a little more. Happy how it turned out either way, even without the rotation. A few more frames added in and the beating heart and rotation could work. Something to think about!
