Berrido I like many of your designs--here is some feedback- Entry #11 I like that you drew in the concept of food into the word nutrition. However, I'm not crazy about that color green as I'm trying to go with a more sage type green and the red could be more of a cranberry vs bright red. Maybe a right slant of the 4u- to set it apart.
Entry # 12 I love that you put a figure of a person in the logo--because it is supposed to be all about the individual person--Not crazy about the font and color. Maybe sage green for the letters and a brownish gold for the person.
Entry# 1 Also-pretty cool-- I like the drop down effect of the 4u -- I'm wondering if there was an outline of an apple around the 4u what that migh look like.
