Female Life drawing will often use a live female nude as the model for the artists. The nude will assume different poses. These varying poses will acquaint the artist with how the human body moves. The muscles and bones cause the skin to slightly twist and pull. This movement casts subtle shadows that the artist may or may not choose to highlight in a life drawing.
Realistic life drawings can almost look like a black and white photo, while a basic line drawing has no shading and no indications of volume. Depending on the level of realism depicted, the drawing will require detail and shading. When an artist uses a live model, it is still within their discretion to add or omit detail. The most realistic art requires the most attention to detail and the longest investment of time, while line art could be imaginative and simple, requiring far less time.
