This one reducing the photograph to what could be rendered in a more painterly manner, I started in Painter. There is also some Photoshop in this as I extended the canvas to the right.

The sky is painted in ArtRage and more of the details of the grass as well as the horns.

Mainly I am experimenting with what the media: that is photography mixed with painting, can do.

Depends upon how much photography you want to leave, and how heavy you want to paint.
