Background and snow brushes.
QU used the Winter BG brush to paint a lively, rich background. If you want a background with a bit less texture, she suggests unchecking “Shape Dynamics” in the Brush Settings panel (Window > Brush Settings) to create a more lightly-textured brush. “The Tilty pencils are perfect for drawing lines and details,” she adds. She used Flakey brushes 1-5 to paint close-up snowflakes, and Flakey Mix for covering the sky in snowflakes of different sizes. For a lighter snowfall, QU suggest increasing the Scatter percentage in the Brush Settings panel when using Flakey Mix. “You can also check Transfer in the Brush Settings panel and increase the Opacity Jitter and/or the Flow Jitter values to create a sense of depth,” she says.
