This and the next two trees were all drawn with a Faber-CastellPitt brush pen, chrome oxide green.  The handling for a brush pen is very unbrushlike.  It's more like a long, well worn, dip pen nib.  It lacks the flexibility of either a brush or many other brush pens I've used over the years but it's a very comfortable pen to draw with and, as I discovered by accident yesterday while drawing in the rain, it works very nicely wet on wet.

This wa a recently pollarded ornamental Cherry tree outside Molly's school.  I had some wonderful sweeping curves to the branches  that just called out to be drawn.
