The original drawing dates from 1975. I still remember I saw a picture of an ancient statue of a Greek, or Roman, horse. I decided to sketch it using, as usual, encre de chine pens and paper. My Father used to collect all my drawing and sketches since a tender age, I still have them in albums, where he carefully would add de periods. After a certain age though, when I was "big" enough, I used to collect them myself.
I decided to digitise it and this time I have used only Photoshop brushes. The results are shown below, in two colour schemes. At the bottom, a scan of the original drawing from 1975.
