About this painting, via Wikipedia:
Bril is seen from the back, and is turning towards the viewer. He grasps the lute firmly, with active and jointed fingers. The landscape painting sitting on the easel is typical of Bril’s early work which is characterized by small figures, deep and shaded foregrounds and masses of silvery foliage, attributes that [Bril] shared with other Flemish painters. This has helped with the dating of the work to ca. 1595 – 1600. 
What I love about this image:
In this self-portrait Bril shows the viewer who he is and what he cares about, art and music. He is relaxed, at peace and sharing his two passions with us.
