This is an interpretive / impressionist sketch.  I may have adjusted the colors a bit much in Lightroom.  I did this at 6:30 a.m., barely awake, and without any light except what broke through yonder window.  Same with the scan.  I’ll check it out later today, when I am at work or something.  Interesting to see the white spots in the scan I cannot see in my gloomy room . . . .
