Thanks for all the options! We like the subtle color elements. The team has been gravitating toward designs with a couple key elements...I thought I'd share in case you wanted to submit add'l options.
First, because our product is a mobile app, we really liked the idea of being able to use the "image" from the logo as the primary element in our mobile app icon (icon found on your phone to launch the app). A couple of your designs look like they'd require a couple changes to make them work in this fashion.
Having the logo to the right or left of the text vs above.
Including the word "Brother" or "Sister" with the text - so we can see how it would look if we customized your design for each audience (while maintaining consistent use of the design).
Emphasis on communication and mobility. Our target audience lives on their phone...whatever design we choose should evoke communication and mobile use if possible.
