After a light sketch with an HB pencil, I start to define the little waterfall with the watercolor pencil. I'm using Derwent Watercolor pencils

After laying down some color, I begin to use a wet, clean brush to blend with. I go back and forth between pencil and brush to produce the art. The more clean water on the brush, and less pencil, the lighter the tone.

I produced very light strokes of the green watercolor pencil and then with a small clean, wet filbert brush, I blend the green tones to produce accents on the water. I've already produced the green foliage behind the bridge, as well the bridge itself.

Using a scumbling technique, I start to draw in various tones of the leaves on the right side.

A little closer look at the scumbling technique for the leaves.

Then, after using a wet, clean brush, I start blending in those leaves on the right side.

Detail of the mossy rocks below the bridge and the turbulent water

Detail of the bridge and trees beyond it. I like the soft watercolor feel of these watercolor pencils. I can break out of my technical rigidity that I'm normally used to and exercise more artistic freedom this way.

Detail of the turbulent waterfall. I don't need or want to draw/paint every single water droplet detail, this piece is loose and allows me more freedom than a technical drawing.

Drawing in the tree on the left side with it's moss

I used a cotton swab dampened with water to produce subtle blends on the tree.

Using a scumbling technique again, I produce the light forest area that's behind and to the left of the bridge

I used a larger wet filbert brush to blend the green scrumbling. I've already started producing the dark branches as tests to see how fine I could get with the watercolor pencils

Further developing branchwork with the watercolor pencils

Very sketchy pencil work on the foreground rocks
