It is not only through the handling of the paint, but the composition of his painting where everything is biased towards the centre. If you want to make the jump towards a more sophisticated composition there are a few things to consider. Choosing a format, square or rectangle
Igneous rocks are created from solidified magma (rock that has been melted inside the earth), sedimentary rocks are created when smaller bits of rock or sand are cemented together, and metamorphic rock are formed when other types of rocks are subjected to heat and pressure.ntrusive rocks harden slowly beneath the surface of the earth, and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock. Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals.
Igneous rocks are crystalline solids which cool from magma: the liquid phase of solid rock. Magmas occur at depth in the crust, and are said to exist in magma chambers, a rather loose term indicating an area where the temperature is great enough to melt the rock, and the pressure is low enough to allow the material to expand and exist in the liquid state. Many different types of igneous rocks can be produced. The key factors to use in determining which rock you have are the rock's texture and composition. Texture. Texture relates to how large the individual mineral grains are in the final, solid rock. In most cases, the resulting grain size depends on how quickly the magma cooled.
