#21: Really like the design. Hate the colors though. Perhaps playing around with a combination (or shades) of red, gray, blue, black .
#16 Moving the circular design from the top to the left might help.
#20 Really like the design. Do not like the colors though. Perhaps playing around with a combination (or shades) of red, gray, blue, black . Also, moving the circular design from the top to the left might help.
#25 Love everything about this design, except that the logo resembles a christian cross. Perhaps modifying the top logo so that it does not resemble a cross, but keeping the idea of the interlocking pieces.
#127 I really like the design on the top, but it is too bulky. Perhaps moving the design to the left of the word "synergy". Also increasing the size of the word synergy.
