This has great potential. A faster shutter would have really defined the frogs legs. They are really too blurry to make a super image. I do like the composition of just the legs in the corner, as though they are jumping out of the picture.
so close to being the best picture of the challenge. I love it and if you figure out how to get a jumping frog's legs in perfect focus I want a copy of it. Jumping frogs are so fast I'm surprised you caught the legs
While the motion blur conveys the jump nicely it doesn't work here (IMO) because too little is in the shot. Perhaps if the whole frog was captured and the legs had the motion blur it would have been a great shot or what you have here but with the legs in focus. Great idea.
