While I know it as the Soul Nebula, it's also known as the Baby Nebula - and from the right angle, it does look like a human baby. If you go with that, this piece of it would be the baby's bottom :)

This is narrowband Ha, OIII, and SII data combined in a way that attempts to approximate their real-world colors, with a bit of artistic license applied. The main challenge was dealing with the stars; they were really distracting in the original image. I used starnet++ to create a starless image, and then used a star mask and PixelMath in PixInsight to blend the stars back in, in a controlled manner. I used that same star mask to selectively de-saturate the star colors to make these narrowband stars look a little more natural.
