I found oil paints have some advantages and disadvantages. When using the brushes, it was enjoyable and quite easy. I liked how rich the paint was and how easily I could mix colors. I think my apple turned out well.
However, using the palette knives was a whole different story. It was very difficult for me to control the colors and the paint and the shapes I was trying to paint. I am not happy with the way it turned out. But I'm glad I was able to experiment with it.
