The picture represents a herd of pigs. They are standing on a small hill and some of them are in the mud. The idea came to me when I was on an excursion and saw a herd of sheep. I thought it would be nice to be able to draw a herd like that myself on the computer. So I sat down and drew the picture of the herd of pigs entirely freehand (except for the curly tails). At first I had a problem with the light source to make the pigs’ shadows clearly visible. After working on it for some time and after several renderings, it finally worked.
