OK. I admit it. I did not see a ram in this particular group. But, to make the composition work, I needed to turn a female into a male.
The change is not as simple as adding a pair of horns. Males have a thicker neck, more robust body, deeper chest. In Lechwe, the head and body can be darker. Since I was in this section of Botswana before I had a digital camera, it was time to thumb through dozens of 4" X 6" prints looking for my lechwe ram reference. Fortunately, all my prints are catalogued and cross-referenced (and there are tens of thousands that I have taken.)
Though most of the details were worked out when I originally drew him, I still wanted all these prints in front of me as I painted.
