Entry #2 is a good start - circle logo has a clearer "v" character; green needs to be a bit darker and prefer that font be all one type (non-italicized). Thanks for your entry!
Entry #9 has an interesting egg and chick motif going for it - as an idea, try making it less "hawkish" by putting three marks on top of the oval to suggest a comb (or sun) and/or try a yellow infusion of inner triangle as well. Thanks!
I wanted to go back and explore entry #1 a bit more - it's simple and has a chicken-like silhouette with reference to a V and Z and a landscape (as well as an enzyme kinetics graph - nice!), but is there a way to design it so I don't keep seeing a snake or turning the image 90 degrees to look like a mouse? I'd also like to try it with the logo next to the text rather than on top. Thanks!
