I've been playing with a new style. Bold, easy to produce, simple line drawing with a Winsor & Newton Series 7, size 1, brush. I like the less is more work flow. I've done several line test with digital brushes and I wasn't in love with the results. It just didn't "feel" right. I think when it comes to creating art dependent on a simple black line, it has to be perfect!! ( ie, Peanuts) I love the look/feel of the traditional brush.
