Among your design, #106 and #107 are potential, however, the heartbeat inside the heart should be updated to real heartbeat, and the heart shape should not look like valentine heart. The color is good.
You are one of the finalist, can you also have a version without the heart rhythm in the middle for the heart especially for #170, #171, #172. If you can make the heart shape less "Valentine-like". It would be nice.
