More waves and splashing water

Slowly but surely the waves are starting to appear, hugging the soft beach sand. I must say, the most challenging aspect of this piece is definitely all the water surrounding this dog, especially the area around the dog's feet. I am finding it virtually impossible to reproduce the water exactly like on the reference photograph, nevertheless, I hope to achieve a good likeness of the waves coming on shore and the splashes of water and sand under the dog's feet.
