Just noticed that my heart shape has some curlies and it is kind of similar to a heart shape in one of Schnick Studios' entries.
This wasn't intentional, I just made a heart shape using the curlies of the "&" symbol in the font I used in the main text (I like stuff to match). I just used the "&" symbol, inverted it, cut off a piece of it, and copied it to make two halves and tweaked it a bit, kinda like this:
