pen and wash work

Here are a few of the paintings I did based on the images in a wonderful book I found this week (again, in the used bookstore for just a few dollars).  The whole book is in Japanese, so I can't give proper credit to the author, but it seems to be filled with work by his students, and so much of it is really interesting to look at and think about. 

I've been trying out a lot of different brushes with waterproof ink, and experimenting with watercolor washes over the line drawings.  I'm fascinated with the idea of being able to vary my line weight with different brush strokes and brush shapes, and with the simplicity in some of the pieces in the book;  many of them can convey depth with just a few washes here and there, or with a stronger line on the shadow side.  I especially like the feeling of drawing with the brush.
