A CIA friend was musing on Facebook that she wanted to get back to practicing her sketching with a purpose. Excellent idea, I thought.
That's how daily drawing helps, if it does. Each effort becomes a focal point for skill improvement: character development/design, composition, color, expression, complications, rendering technique, observation and so on. Without the "purpose" part, it's easy to practice unsuccessful techniques and make them habit.
The above drawing was an answer to a blog challenge on Valentine's Day, and I wanted to work on what I think of as the design of cuteness. I also tend to stop my sketchbook scribbles with the character itself, so I forced myself to add at least the hint of an environment.
