The weight of type is a little thin, and hard to see as it is without its grey color and grey background minimizing its appearance. Ever thought of making the type a little heavier, including the mini-circles/o shapes? I keep looking at this and thinking of thought bubbles, water bubbbles, conversation bubbles...it would be nice to see this in color variations as well. I like using gradients to imply subtle movement...those bubbles look like they're moving upward to me. Have you considered using differing colors to highlight and draw attention to this aspect of the design? Tag line is a little small in proportion to the name -- could use some balance in size [be larger] to shrink better. Overall, nice work.
Thank you McG and everyone for their kind words.
