Well... I think it is!
I've been away in Turkish Cyprus for the past week and had my camera with me literally every moment of the day for seven days. (I went there to take pictures, not sightsee

. Out of hundreds and hundreds of photos, only a few come even close to what I think you're looking for (and I'm not even sure on those).
I had one other that amused me of a big street dog and someone's puppy's first encounter -- friend-or-foe sort of thing -- but after going thru all the instructions and suggestions, I came to the conclusion that it's lacking at least one of the elements, even though it was definitely a decisive moment for them

(see below).
In any case, even if I had gotten more appropriate pics, I used my D70 exclusively while on Cyprus so wouldn't have had any Eligible pics, anyway.
Very challenging, instructive Challenge, though, I must say!
Helen
And only 24 pictures to choose from in the eligible
C'mon guys it's not that hard !
