I chose to make a butterfly as the symbol for cancer survivors (metamorphous into a new stage in life) as well as attempting to symbolize breast in a very subtle and tactful way in the lower part of the wings. The upper body is in a heart shape to show "caring". Also, please note the the wing pattern is meant to signify different size. Also I kept away from making the inner wings concentric, so that the drawing looks more organic and show different shapes (this is more noticeable in #40, but I can also do the same for the other designs. Your thoughts and revisions are most welcome.
