Nice idea Richard, and a great B&W image. Excuse me if I am misinformed, but I understood that it was the rear legs that went missing from frogs in France.
You might be interested in the fact that I entered 6 bw in the fair and two won first and the other 4 won second in their categories. The student represents the teacher well.
@randystreat I found Mr Frog (with a number of friends) in a puddle of muddy brown water in the forest - the lines are the shadows of the tall grasses surrounding the puddle.
Like you frog.
