Avoid introducing any color tones into the image, as well as the use of shadows or gradients. There's no need to include details in gray tones or complicate the composition with shadows. Exclude any representation of additional organic elements, such as flowers or other animals, to maintain focus on the mandala and the geometric figure of the bear. Additionally, do not use thin lines or messy patterns in the design, and ensure the image does not have a shaded drawing style.
