Earlier (left) and later (right) versions are shown above of a head / type study modeled after a foreground figure in a Bruegel painting. I isolated the figure's head, placed a halo behind it, and treated its features in a way that might be appropriate to a portrait of the Apostle Paul or the prophet Jeremiah.
The left version was done at a quick pace, using a kind of shorthand for a model that would be used to create a larger, more developed painting. The right version, is a reworking of the same image, slowing down the pace in order to develop representations of light and form. I'm not sure what pace is better for me. The slower pace is more familiar.
