Agreed. Water is magnificent.

I caught that it was cracked earth/mud.

My nitpick would be the texture under the water. If it is a moving river, that ground would not be cracked, but instead it would be fairly smooth and depending on the speed of the water is likely to show lots of rocks and pebbles (depending on the terrain the river is cutting through). Also, the water needs to be deep enough around the piers to handle the watercraft, but not knowing what the craft will be that is hard to judge in this instance.
