Love the bold simplicity of #4 - the graphic treatment evokes an arrow without being an arrow, has a bit of an aviation feel to it (which I like) and movement - Relationship between VECTOR and Branding is good in terms of size and color (or greyscale), not sure if the lower case in the Vector and all uppercase in Branding is right - would like to see variation on this. #8 is similarly interesting, red adds a dramatic "pop" but the multi color diminishes the overall impact of the graphic vs #4.
Thanks for your creativity and submissions! This is my first LogoTournament and I'm just learning how the rounds work, so I apologize for not getting you feedback sooner for you to participate in top 5.
