I wanted to add some Renaissance artwork to a game I'm working on, so I practiced some more on my dos-vga style.  The idea of the method is to imitate some styles in early 90's vga by taking a photo (or in this case a painting), doing a nearest-neighbor resize, selecting a palette from the resulting pixels (with longer than typical ramps), and then coverting the rest of the image to that palette by hand while fixing up the image.
