Hi Renato, I enjoy your class very much. I tried to understand the process and it helped me while doing each layer of the painting, I have difficulties in doing less brush strokes, and identifying light and shadow. I also had problems when adding the salt, I didn't add enough water.
I love to put details to the drawing because it gives it highlites. I did the drawing by myself tha's why I did not put the sign to the crab. :)
I will try to apply the same process in other drawings to see how it comes out.
