#15 & #16 the lettering stands out, the yellow and brown seems too obvious towards a brown monkey and a yellow banana. I don't see these as being the theme colors for my company. #15 I like the way you have formatted the "think before you eat". The monkey in both entries is a bit on the comic book side with the head scratching and the banana. I am looking for something a bit more abstract.
#10, I really like the font colors you picked. The font style on the word "monkey" is a bit too casual and doesn't seems to go with the other fonts. The monkey icon is a bit too large. I like him holding the fork and I like it being a silouhette however using the "thinking" monkey is a bit obvious.
