Really like 108. But we're back to thinking about how things look on a white background. Can you do the #108 on white and see how it looks? And try one in orange, green, and blue if that's easy to do?
If the logo looks a little thin on the white background, maybe try thickening the lines and even taking out the bubbles. Definitely like the fading waves that emit from the top. Thanks again for the entries!
