I think the sphere approach provides a nice "mark" that can be used effectively in web and other media however the Nation just seems to hang off in space
I like the clean lines of #18 along with the non cluttered background. I am leaning toward a chiclet shape (box with round corners). Can you do a couple of versions in that shape? Also with a font that has the N and P separate. Let's get the design right and then we will play with some color treatments...nice stuff
I like # 54 but the P looks too much like a question mark. Can you also do a treatment where NP Nation is on the same line and in a rectangle container. We have some other brands that have a longer word than "nation" and a similar look would be good. If you win the competition we would work with you on these other brands as well.
