Hey there - thank you for the feedback and the ranking. Here are two iterations, #28 and #29. I focused on making the "C" pop a little more by shifting its placement just a bit. Let me know if this works for you. For #29, I filled in the negative space in the "B" to follow the theme. Just a professional way for me to say I added the balls - lol.
Let me know your thoughts and if you'd like to see any other changes.
Thank you!
Ignacio
