The heart symbol is a bit of an uphill battle on our approval team. Some of us like it, a few more do not. For this reason, a fully formed heart graphic as it used in these first four entries (55-58) will likely not be acceptable.
The squiggly hand in 55 looks a little awkward. At first glance it looks like a tadpole tail to us. The logo needs to look good in small and large settings.
Can you focus on making the text not so heavy, use a more greenish blue and try to use a different scheme with the ripple effect (as stated in out brief) or just something that demonstrates small gestures having a far reaching impact?
