Visual Language- quality of line pt.2

These are the drawings (of people in the room) created from using a line qualities from tests. I did a lot of drawings and most of them were very fast- and I wasn't happy with them- like this first image. 

After a while I slowed down, and concentrated on the subjects a bit more- and this created the drawings I was more happy with. I did the drawing on the left first- although slower it was still lacking observation. The second (on the right) is better observed and I think the simplicity of the line is better.
