LEARN HOW TO DRAW
You will be amazed at how much learning how to draw will help improve your oil paintings. In fact, years ago art students were not permitted to paint until they learned the fundamentals of drawing. Drawing gets you more in touch with value, line and form without the distraction of color. Find a good book on drawing fundamentals and start there.
LEARN ABOUT COLOR
Nothing can confuse a beginner more than color. You need to have a good understanding of color theory if you intend on producing high quality paintings. Concepts like color temperature, hue and intensity are very important and should be studied. Once you have a good understanding of color theory, you must then learn how to mix your colors. There is much more to color mixing then meets the eye. For instance, you cannot mix any old blue with any old yellow and get the perfect green. Certain blues and yellows behave differently than others, so you must learn about the properties of each color.
PERSPECTIVE
Perspective in painting is one of the biggest hurdles for beginners. Sometimes a painting just looks “wrong”, and often it is because the perspective in the painting is off. Learning about perspective will teach you how to properly translate a 3-dimensional world onto a 2-dimensional canvas or other support. Learning perspective is a necessary ingredient toward producing convincing oil paintings. There is of course an exception to this, if you are producing an abstract work and your intentions are to warp the perspective.
MATERIALS
Materials to an oil painter are like what a guitar is to a guitarist. A guitarist cannot play without his instrument nor can he play without understanding how his instrument works. Your painting materials are your instruments. They are what enable you to express yourself, so learning more about them is an absolute must. Learn about the different kinds of brushes and what they do. Know your paints. Not all colors behave the same. Some are more transparent or opaque than others. Know your supports and the difference between them. The list goes on….
