Hi Jeff,
Thanks for submitting your designs. We really like the Y you've created and these designs are a great starting point. #15 is our favorite.
First of all, we think that the colors need to be a little stronger so that they show up against the white background more. Also, we've enjoyed the way some of the other designers have used two distinct colors for the two different words - could you try that for us?
Finally, we'd like to see another font or two. The font you've selected is nice - it's sleek but possibly too cosmopolitan for us. We'd prefer somehting a little more flowing and less modern.
Thanks for your work!
BYoga
