hello henry,
Thanks for your revised submissions. I moved 350 to the #1 rank, but there is one problem we need fixed with these designs.
The image of the period and the first ring of the ripple resembles the symbol on the muslim flag of the star and crescent moon.
See this link....

Can you work on this and get back to us asap. If we can fix, you are the winner. But we cannot accept in its current form. Thank you.
