#10 and #11 are quite interesting but I would try a different character as this one is associated to a female. Perhaps a more cartoon or abstract mascot or character to create a more general identification. Also it's portraying a bit of sports image to me.
#16 and #17 might be more interesting without the character with just the clock as it's a bit too busy.
One idea that I had looking at your designs is having one or two tiny characters on top of the words "gap" and "job" trying to force push the letter "A". Maybe with a hammer or something like that.
