Playing with Brush Pens

I decided to pull out a few of my Kuretake Zig Real Brush pens to play around with and work some quick sketching.  This is something I need to practice to feel in better control of the pen and how the ink washes out.  I was a bit heavy handed with applying my brush strokes.
