I hear a lot of talk about "lift," but would love to see that process explained in greater detail. I get the idea, and have practiced a bit of it in the past, but would like to see other methods.
I enjoyed seeing information on layering color. I haven't seen a lot of that yet in the other classes I've taken. The sphere exercise was very interesting and helpful.
I got a little carried away with my feather, but I've never painted anything like it before, so it was fun. It makes me want to do more.
