1. the picture at the top left remains me of art work done by Andy Goldsworthy, where he uses tree branches and twiggs and connects then in a form of a circle.

2. the sand or pebbles are used here to show how earths surface is as for as sand is concerned. To get the right amount of the substance to looka s it does takes skill and precision.

3. Now this also remain me of Goldsworthy work. This is a nest in a tree. Now the artist in this one comes from nature; a bird. It takes time to collect the twiggs and however, by nature, the bird can precisely construct a semi-round formof shelter.
