I really like this idea, it's a good concept!
One criticism though, I never really saw the negative spacing, even after it was pointed out. Probably because I was still half asleep at the time, but now that I can see it I understand why. The proportions of the pencil are way out, at least in your first one. I think you've realised this though as in your second attempts you have enlarged the triangle. I am wondering though if it might look more natural still if you reduce the crown to 3 points instead of 4. You could also fix (reduce) the tracking between the K, I and N which would also help with the overall proportion. I would definitely stick to the curved crown as well, the third (furthest right) crown looks the best to me.
As for using the term creative I don't personally mind it, however from a clients point of view it is a bit vague and as others have stated, you might want to use something a bit more specific. Design or designs would work well.
EDIT: Damnit, stop bringing up old posts!
