These are really promising. The Public looks a bit corporate, though and it kind of reads like "Public Architects 47" instead of "Public 47 Architects". I really like the 47, though. Consider locating public and architects above and below the circle. Also consider arching either or both "public" and "architects" along the top and/or bottom. Best of luck. Next ranking will be at 3pm.
Nicely done. Suggest exploring versions in black and white--take #82 and change the grey to white; take #84 and change grey circe to white and "47" from white to black. Great work integrating my feedback so far! Next ranking to occur 10am PST.
