Positive / Negative Space

This poor old bush struggling for survival, 

at first appeared to be a rather uninspiring subject. 

However after some cropping 

and further thought 

I started to see an idea emerge.....

the interplay of positive /negative use of space.

In the top half of the sketch 

I used the traditional 

light (leaves) against dark (background).

While on the bottom half 

the shadowy darks play against the light reflections.

I worked on a midtone pastel paper 

with watercolour pencils and crayons 

to enhance the contrast.

Although as I review this post
I think perhaps the cropped photo 
is more successful than the sketch.
In the photo the bright greens 
allow the top to be slightly more dominant 
giving the eye a place to rest 
whereas in the sketch
both halves are equally strong
making it somewhat unsettling.

Such is life!
