Summarize this article in one sentence.
You may choose to draw one of the dresses she wears in the movie or invent your own outfit.   Anna often wears modest blue or green clothing, with flower motifs or stripes. If you layer her clothing, take note that cloth has volume; it will not be perfectly flat. For example, the shoulders on the vest should be a little higher than the outline of her body. This will give your drawing some weight. Follow your initial outline for her shoulders when drawing the vest. In the center, draw a large U-shape to connect the two sides of the vest. Add flowers or other details as you see fit. Go over your drawing and erase any trace lines which may be intersecting details like her hair or clothing.   Use thicker lines to indicate the shadows under her chin and her eyelashes. You may wish to use a pen with black ink, or make some of your lines colored. For example, you can use a deep orange for her eyebrows. Or, you may wish to stick with pencils. Hide or erase any leftover sketch lines.   If you are drawing digitally, change the background color to something other than white. This will help you use more contrast when you color, and the image will look nicer. Decide where your major light source is coming from. This will help you with adding shadows. As a general rule, the closer part of an image is to a light source, the lighter it will be. Choose warm, peachy colors for a glowing complexion.  Don't be afraid of contrast; shading timidly is a common beginner's mistake. Pick a medium brown for the deepest shadows. This will help you get a more detailed drawing that looks close to the version of Anna in the movie. You want to shade in the direction that her hair falls to help it look natural.   If you are drawing digitally, make a new layer for the hair. Drag your brush in the direction her hair falls. When shading her braids, make the darkest part the top and bottom of each section, and the brightest part in the middle. This method of shading will help her hair look healthy and clean. Move on to her clothing and the whites of her eyes.  Her shirt needs less dramatic shading because it is not the focus of this picture. You can use a dark green for the vest, and a light blue for her shirt. To add depth to her eyes, start with a grey-brown color and go lighter and lighter as you move down. This will mimic the shadow caused by her eyelid and eyelashes.
