Hello Nabuy83,
Thank you for your entries, we really appreciate the variety of the designs. We like the look of #10, but the round circle with a smile makes it similar to one of our competitors logos and we would like to be more unique. Could you possibly change the shape but keep the idea of the braces/stars as the smile.
We also like the clean look of #7, but it may be a little too simple. Possibly changing the font and making the smile more stylized or adding braces might help.
Thanks and we look forward to your revisions!
