Student RoarLogo Design Contest

I like these concepts. Enjoying the color choices and the hidden face with the first two. Do not like the gray background. #16 is nice too. Can you make the face inside the "O" less ferocious?

The gray is not part of the design its more for color contrast. As far as a less ferocious roar is kind of a double standard. I will see what I can do cause a roar happens as an act of ferociousness.

I guess my feeling here is that it looks more like a dog roaring than a bear. Anything you can do about that? I think this concept is quite strong.
