Detailed Sunflower

Today we’re drawing a massive sunflower packed with detail and repeating patterns. If you enjoy getting lost in line work and relaxing into slow drawing, this one is perfect. We’ll build it up layer by layer using brush pens and fine liners to create loads of texture without overcomplicating things. This post is for paying subscribers only Upgrade Already have an account?
