Thanks for the new designs. One of our favorites (entry #17) has a resemblance to the logo for a grocery store chain in the US called Safeway. Take a look at that logo and see what you can do to pull yours farther away - maybe extending the curve of the "S" between the ying and yang. On the most recent entry #43 looks great. A few suggestions - lose the "inc" in the name and see what you can do with just white space and no outer ring around the symbol. You are definitely one of the best designers on our contest in terms of delivering what we are looking for and are very close.
Another thought too - if you can take entry #11, lose the '"inc" and see if a white medical cross could fit in the blue field beside the wave, in the curl, or someplace (might want to try a few options) and maybe take some of the curl out of the wave, that could be exactly what we want.
