For #2 and #3, we like the general concept, but the letter o is sufficiently distorted that it is hard to read. For #2, we would prefer a red instead of orange. Also, gradations of the graphical elements (one lighter, one darker) would be interesting.
For #4 and #11, we do not like the graphical element above the name, but if there were some way to work these elements into the name, that could be interesting.
#21 is interesting, but the O is too busy For #22, try moving the red arcs to the right of the word. We like the rounder look of the leading C as opposed to the flatter looking letters.
