Pronghorn impressionism

Pronghorn normally are found in an almost monochrome environment, depending on season...greens or yellow browns. Now is the shoulder of the seasons between summer and winter and vegetation assumes other, more subtle hues. I kept the lens open for a shallow depth of field, hoping for a background of color accents, reminiscent perhaps of impressionism. Image is processed without in-camera sharpening, then sharpening applied only to the pronghorn to help lift him from that background.
