If I were on the jury I would put mine in 3rd place.  I felt I did the actual throw fairly well but that's all it was, an exercise.    Mohviv's would come second - it had a story which was clearly told, and a little twist at the end with the onion tears.  F and S  Studios would get my vote for the gold medal, because it both tells a good story, and does the most with the knife throwing.  It had that nice little toss up in the air and catch, which built up to the main throw.  A throw is such a quick thing, so adding that gave more time to get a sense of the weight of the knife.  And the timing felt good on the throws.
In the end it's more about participating and pushing our animation  skills than winning prizes, and all of us who actually did a submission are winners.

Hey guys, it was great fun to participate - and for me, it was a great reason to get into stop motion again. I fully agree with all of you and also see these challenges as nice little encourages to practice some animation and improve. Thanks for all the comments and thanks to FandS and Nick for your contributions. I look forward to the next challenge, really great topic Marc. It will be interesting to see how this will be tackled!!!

Hah, don't worry Marc, everyone did a good job so it's not like you had an easy decision to make.
