Let's work with #31. I like what you're doing with the DZ. Give the Z more punch so you can tell its a Z. Play around with a stronger font selection and better color coordination to match the test site in my brief.
Let's work with #95. I like what you're doing with the bar lines for the D and Z. Give me some other options for making the Z stand out instead of it just being a backslash through a box.
