Hi, your entry #39 is one of my favorites because of the interesting middle part. I would like to see the grey edge around the design thinner, or with more dimension. Also, if you can try slightly different fonts, that are elegant but slightly thicker so they will be easy to read from far away.
I just received feedback from people at my company. They also like your entry #39. What they would like to see changed (in addition to my comments above) is to remove the feather look from inside the circle, and to make the T's have less swirls.
