Here is a painting completed last year of an unusual SIGINT aircraft used by the RAF. The Raytheon Shadow R.1 is based on the twin turboprop Beech King Air and closely related to similar types in use with the USAF. It is 70cm x 35cm.
Those mountains and angle of the plane! So simple but so intense!
Plain sky contrasting the intricate mountain patterns. But simple in color. Almost monotone. Duotone. Beautiful.
