Here you see the first marks to establish the subject. I had roughly sketch this with paper and pencil so was confident enough to go with this image size. Using the Acrylic Black paint I suggest some of the markings on the leopard. I used acrylic because it dries very quickly and I confess I was in a hurry to get to the oils. You can speed up the drying time by using a hair dryer if you wish. At this stage I really want to establish the pose and make sure that my drawing follows the photo fairly accurately. Past experience tells me that I will have to go back over the markings as the painting progresses and I begin to look much more intensely at the photo. I should say I have no hang ups about using photos for my paintings, provided they are MY photos. Other photos from the net, books or magazines I use only to learn how to draw the subject.
