There are lots of art challenges around at the moment, this one is from the Facebook group Purely watercolour. I used some tubes of W&N Cotman watercolour I found while tidying my studio. The pigment is not as strong as artists quality paint and it has a tendency to go muddy which I struggled with. I tried to rectify it using a gel pen and some white gouache. The photo was taken of one of the islands in the Venetian lagoon, I forget which one.
