I probably used a little too much oil in my copy as I was trying to get a "non brushstroke" look like he achieved. Of course, I now know that isn't the way to achieve that effect. Also now, I don't have any interest in that effect. So, that's the way it goes.
I find it better when copying a master to learn, to try to have a goal in mind rather than just blindly trying to copy them for the sake of copying them. Try to learn how they did or achieved a particular thing. Such as a certain effect, how they used lines, how they balanced shapes against another, how they could make skin glow - are just a few that come to mind.
