Entry #15: can I see this rotated similar to Entry #16 with the right side of the icon aligned with the left side of the letter "M", to encompass the "SO."? I like the direction your taking this. I'm intrigued with the way you incorporated an abstraction of a building into the icon. Would you mind squaring off the bottom of the icon on Entry #14, as well? Nice work!
I like Entry #12, as well, but the "MOD" is a little difficult to read because of the black directly on read. Plus, the font sort of makes the word look like "MOO" instead of "MOD". Nice & simple though!
Can you do another variant of entry #23 with "SOUTH MODERN DESIGN STUDIO LLC" on each a separate line aligned at the top right corner of the icon, to somewhat fill the space on the right side of the icon? Something similar to what the designer did with these words on my Entry #2.
