Drawing from observation skills.

Accurately creating a drawing from observation takes a variety and multitude of skills, some art related and others in a broader sense. To accurately depict a "still-life" most preeminently takes an understanding of the set-up, how to draw the objects, and your skills as an artist. Artistically, it takes an understanding of the foundations of what you are depicting and their locations and size (ratio to other objects); the tools that you are utilizing; when and how to use value to depict depth, mood, color, texture, etc.; and many other essential foundations and detailed skills to draw effectively from observation. The other skills, not pertaining to art "specifically," consist of knowing how to focus intensively (for an extensive period of time), the physical ability to stand in one spot for substantial spells of time, and an enthusiasm for the task at hand. To conclude, drawing from observation takes these two essential classes of skills, artistic and those not concerning art, and to the extent utilized, is manifested in the artist's work.
