I went walkabout (in Charity shops) and got inspiration from Aboriginal art ...

I recently picked up an original Aboriginal painting on canvas for a few pounds in a Charity shop.
The artist is Minnie Ngwarray Morton one of the artists of Ampilatwatja in the Northern Territory of Australia.  Interesting to read that artists from this area  mainly depict medicinal plants and herbs arranged in attractive patterns. This piece  has a  terracotta coloured background, and  limited palette of blues, yellows and greens.  I've never been to Australia, but have "explored" by means of stamps, and loved creating an  Australian flag collage some years ago using stamps showing the wonderful and  varied landscapes of this vast country.  When I think of a famous Australian landmark, Ayers rock, or Uluru,  springs immediately to  mind. It's the largest monolith in the world, and appears on a stamp issued in 1993, shown below with a few others I'm hoping to incorporate in a stamp collage version of Ayers Rock I'm now working on.

 I'm  gathering together mainly Australian stamps in appropriate colour tones, as well as also searching and researching  Australian plants on stamps  to include in the picture's foreground, along with a few trees and maybe some wildlife. I also found a series of stamps showing Aboriginal rock paintings art, issued in 1984, some of which may also find there way onto the rock. 

I must keep at it and not be tempted to go walkabout again for a while!
