#9: I like the script for healing hands.
#8: I Like the size of the healing hands
#7: I like the lay out of the three different characters
For All of them < I love the concept of over laying different species but it needs to be more harmonious, and slightly abstract. Not so abstract that you can't tell what species you are looking at right away, but abstract enough so one image flows into or with the next image. Could you put a dog,cat, bird, lizard? That heart is a nice touch but only if it can flow with the image without distracting from it.
