I often find it hard to stop with one attempt - that's the nature of watercolours - you have to explore the process through more than one painting, as opposed to acrylics, where you develop a work through layers. As is often the case the first one is the best.
This is the first one I tried
Tried a bigger one, but the salt didn't work for some reason. I must explore that further. Obviously the ambiant temperature and humidity will affect how the salt pushes the pigment, but the weather had not changed to any great extent between these two paintings.
