This is a good B&W challenge shot. The shark is sharp and clear. At first I didn't notice the people in the background until I read your post. That's when I saw the faces. Good luck in the challenge. It's a good entry.
Awesome shot Jimbob - actually outstanding!!!!! Great capture from nose to fin - he looks great in profile - you can see his ribs and gills - he even has some freckles or beauty marks - the people on the other side look as though they are amazed as well - Excellent!!!!!!!!
My thanks to all who leave comments for my work and to those of you who like one enough to make it a favourite. To touch just one person that way makes each image worthwhile. . . . . . . . . .. . . . "The question is not what you look at, but what you see" ~ Marcel Proust
