#1 I like it, but colors are so light ... the logo there is not strong!! I said orange as one of the colors, but mixed with that green lose it too power
#2 I like the bag but not the hand on it... so "comic" and not iconic. Again the mix between orange and green doesn't like me.
#3 better than first because the contrast, but lacks soul
#4 Really don't like it, my nephew 3 years old, can do it better, sorry
In general: I do prefer flat colors, something warm, but easy. I like the logo of http://www.chefboyardee.com/, because is warm, friendly, happy... but I'm looking for something a bit more simple, easy to use in one single color I want to see waves as in chefboyardee text... maybe it will works
