Thanks for the clarification of your earlier design and submitting a new version. I like how you incorporated my feedback into a design that is relatively simple but conveys the messages I'm looking for.
Good use of color and creating image of progress.
I like what you've created so far.
I will be getting more feedback from my associates tomorrow and will pass it on as soon as I receive it.
#52 seems cleaner because the arc is under the letter "C".
#71 seems to have the "C" cut off by the arc. But, I like the attempt to create a 3D image. Could you try modifying the arc so it leaves the 3D look without seeming to cut the letter as much?
