#4 and #5 are spot on with my original idea. Can you try two things? 1) Bring the infinity symbol to the fore and put the "8" behind it. And can you try a slightly brighter color/shade for the 8? Much appreciated
You did exactly what I asked for and I thank you for that. At the end of the day, the client wanted to go with something a little more abstract. But wonderful job, nonetheless..
