#4: My favorite as far as the blending of 5 species (I think) into round hands. This is the direction I like but looks a bit busy. I want something to POP out at the reader and be memorable. Have the animals blending together in a more abstract way but not so abstract you can't figure out what they are at first glance. Also make the figures more soft. No hard edges or lines. The green head does bother me. Think it would look much better without the head. # 5: You have the right concept. Abstract but too rigid. The dog also doesn't look happy.
#4: I like a lot. It captures that I see all animals. My husband thinks it looks a little busy. Could you take off the green head. It is distracting. I think would look better.
