Thank you so much for your creative ideas. Can we try it without the words D Squared and use only the mathematical symbol or a representation, thereof? Yet still incorporating blue and orange, and using the initials S and M. Like the d within the d in number 22 a lot. I see the S in numbers 21 and 22. My guess is that I am missing the M. Thank you again so much.
Sorry, I mistyped.....I see the S in 20 and 21 but no M. In 22 I don't see either of the letters. I like number 29 a lot with the d within the d and the use of the initials. Thank you.
I think that we prefer the style of the d within the d as in 22 and 29. Could you try the initials within the lines of one of the d s instead of within the center? Hope that makes sense
