I'm trying to use Buncho Oil Pastel color which is typically hard oil pastel, but it is cheaper. The way of coloring and blending is also different from the softer oil pastel like the one that art students use. in order to get used with this oil pastels, I did some oil pastel coloring practice... and here's another practice stuff...
Apple in the morning - Doctor's warning
Roast apple at night - starves the doctor outright
Eat an apple going to bed - knock the doctor on the head
Three each day, seven days a week - ruddy apple, ruddy cheek"
