I really like where you're going with this logo. Could you make the bottom of the "O"/ wave flow more into the curve so that the part that crosses looks more like part of the wave? Also, could you add another color in the design to give it some more contrast? Maybe a black/white version too to see what it would look like if we can't print color sometimes.
Again, I really like the direction you're headed with this. We are just running short on time for this open phase. So I will try to make sure you are a top 5 designer so we can see more of your work in the next phase.
Cheers.
