Our panel has reviewed these and here are the comments:
The panel liked your sizing. Both of the "D" logos were not well received, as they appeared more as a sideways "U."
#29 - colors were a little faint. A slightly brighter color mixed in would help.
#30 - The bold in DAVIS was preferred to #29. We liked the more modern font styles, but the font needs to convey confidence and security. a Tweak here wold be appreciated.
