Veeery interesting, I see all brush strokes but it creates something very concrete, bat, this style remind me Rembrandt and some of his portraits, together with maniera tenebrosa it gives amazing mood.
what is the shadow of the night without it's flight? a broken being whose pain draws you heart strings into it's grasp and tugs repeatedly at them again and again until your a crying, sniveling mess of sobs and soaked tissues...
At first, i thought it was a picture of a real pipistrelle skin and was preparing to comment that I have one too Vey beautiful painting, i love how the light shines on the left wing, the colours, composition and how well you represented the anatomy. All in all a great study of a great animal.
You're right, I can't know In my language a bat has got the female article. But I don't know why. I'm happy that there are bats in my neighbourhood Every bat species in Germany is on the red list (=endangered) so I was sad when I saw the painting.
