#30: We like the creative interlocking of the D’s but we want a strong presence and by tilting the Dr., it’s a little too playful. -Nice classic font choice, so maybe try some other creative treatment of the lettering to creative a distinctive look with the classic font. -The other entries #31, 29, 28 aren’t quite hitting the right tone with us, but the creativity is there. We aren’t wanting crosses, and emphasizing the period doesn’t quite work, so maybe avoid that. And the R in the D makes it a little tough to read. But the creative potential is there, we’d love to see what you can do with #30.
