Duck, Grapes, water, blue background. Everything's there. This is a very simple shot and I like that.
I like the angle and framing/cropping you chose for this. The duckie being dead center doesn't bother me, but you could play with offcentering the duck a bit to see if that adds to the shot.
Focus and clarity appear good to me too. I like how the upper grapes are out of focus but the duckie is in focus. Nice DOF.
Lighting is good. There are some shadows from a couple of grapes, but that's nothing seroius.
I wonder about the background though. Could there be something to make it a more bright blue? This blue seems dull/flat. The color of the duck is great, nice bright yellow. I think I would like to see a nice bright blue to compliment that.
Overall a simple fun shot. I like it.
