Here are some options with the revisions you requested:
#82 - replaced the cat with the head of a child. I made the child gender neutral, but if you prefer it gender specific, or older or younger, just let me know. I'd be happy to change it.
#83 - switched the position and the color of the child and dog
#84 - switched the color back to the original for the dog and the child, but kept them on the switched side.
Please let me know if you'd like any kind of revisions to these options. I'd be most happy to make them. Thanks for the feedback!
This is a slight modification of the first-ranked design, #86. I worked on the curves of the wing, especially the top part, to better replicate the curves of the heart shape and make the wing part more graceful.
