I like #14 a lot, but I think the title could be incorporated into the design a little more, to make it seem more interactive with the creativity theme.
#48 -- This is great! I'm still not too crazy about the font though, can you try something a little more like #23? And maybe NC could be a different color or italicized or something so it stands out?
#58 -- LOVE this. Particularly the person as the "i" in inc. FANTASTIC! Do you think you could change up the colors just a little bit, so they're a little bolder? The top half of the color wheel seems to be brighter than the bottom -- the brown in particular is a bit too drab.
#81 -- Fantastic!! The changes look great! Can you do something to make the little person (who I love) look more like an i? Maybe make the head a little further away from the body, or a different color?
