You’ve captured nice reflections of the sun above the ducks. Good composition, balance and unity and a slight diagonal line of the ducks in foreground lend movement. Repetition also creates movement. However, the slight forward turn of head of the far right duck slows the movement out of the frame. The smaller ducks in the background create depth.
I was wondering why you left so much space in the foreground, especially when it is out of focus and full of floating debris and did not accentuate the beautiful reflections of the sun. Although I like the composition of the ducks, I think moving in closer and focusing on one subject would better meet the assignment (maybe focusing on texture or capturing part of the body that is interesting). Also the duck that is making a landing or getaway is a distraction and stopping the movement of the far left duck.

Move in closer if possible (was your zoom maxed out?). Remove undesirable distractions.
