I like this series (#53, #54, #55). I don't know yet whether I like just one dot over the i, or many. What I would like to see, though, is to make #53 and #54 similar to #55 in terms of the 3-d lighting/shading. I like that #55 has a more 3d feel to it, but I'm not sure the coloring (with the lighter blue) is right. I'm not quashing the other color, am just not sure at this point.
#53 - I'd like to see what happens if we add the CRI logo mark -- either as the whole circle with four dots, or just the four dots -- in the logo mark you have created. Please try versions with blue 282 or the complementary orange. THanks.
