The exhibition by Riccardo Guarneri and the Chinese artist Qingzhen Han is underway in London, at the Rosenfeld Gallery until 21 March. Both artists are characterized by evanescent painting although the sign of Qingzhen Han is more marked. In addition, while Riccardo Guarneri delimits and closes his works within straight lines, the artist Qingzhen uses curved lines drawn haphazardly without the rigor and rationality of Riccardo Guarneri.
