Where is that taxi

Where is that taxi? Two ladies waiting anxiously for a taxi to come by. When I am out and about I am always on the lookout for interesting subjects and people. This little watercolour study 10x9 ins on the reverse side of a piece of Waterford Saunders watercolour paper. I tend to use heavier pigment washes, with less water when it comes to this type of paper. The reason being, that the painting can be done in one go without any further washes.
