#5 can the black teardrop in the circular image be more arrowhead-like, to represent movement? Also, I can sort of see a 'C' and 'I' when I look for the 'K' in the circular image, perhaps enlarging the face or somehow integrating the face with the bow (speculating here....). I also wonder if an effect like a button across the image and text to give it some depth would add to it. I'm liking the font and colors.
#21 I like this one, it has a feel of the soviet propaganda style - if you know of the style I'm thinking, is there a slightly bolder version you might do as a comparison?
