Michal Jasiewicz is a Polish architect whose avocation and passion is painting in watercolor.
Like other artists trained in architecture or architectural rendering, Jasiewicz’s work is characterized by a foundation of solid draftsmanship that allows his to apply his colors freely without losing the sense of underlying geometric strength.
I particularly like that characteristic of his work as well as his skilled contrast of hard and soft edges.
Jasiewicz conducts workshops in Poland and elsewhere, including an upcoming one in Valencia, Spain, 13 November – 17 November, 2017. (There are additional examples of his work on the workshop info page.)
There is a brief interview with Jasiewicz on Art of Watercolor.
