This needs an open-mouth shark or at least a fin on the horizon :) As for the technical aspect, the lighting is a bit too bright. A little later in the day would have been better.
Nice idea. A couple of small complaints - the detail is lost in both the highlights and in the shadow. This picture could've been more interesting if you'd thrown a stone in the water to make a splash or some ripples
Umm, what's the point? Sorry, this isn't working for me. Those words meet the ironic nature of the challenge, but did you mean to show something unpleasant happening after they were uttered?
