Tulips are cup-shaped flowers. They have six petal-like structures, but only three of the structures are true petals. Tulips are composed of three outer sepals, which were the outer cover of the bud, and three inner petals, which are true petals. Knowing botanical structure helps create scientifically accurate illustration, because the two parts may have slightly different coloration, shape, and texture.
With bullet-pointed 2H or H pencil, measure the outer dimensions of the tulip and draw a rectangle. Then measure the tips of three sepals and connect them in a triangle. Do the same with three inner petals. By examining the angles and crossings of the triangles, confirm whether their placements are correct or not. Now, sketch in the sepals and petals focusing on accurate position and proportion.
With a pointed 2H, and using substantial pressure, draw a detailed shape of each part. For foreshortened shapes, add some shadow early on, which helps to better show the form. Carefully observe any tiny vein lines and their direction on the petals and sepals and mark them. They will make the curves look organic and realistic. After the final lines are drawn, erase the initial lines.
Trace the drawing onto good-quality paper if necessary. Now, add shadow on the inside (concave side) of the petals and sepals. There are two concave shapes created by the inner petals and outer sepals. Observe carefully where the darkest shadow occurs.
With a pointed pencil, draw vein lines following the curvature. The fine lines might not be very visible when the drawing is finished, but they enhance its formation. By doing so, details and textures can be added as well.
Add shadow on the outside (convex side) of petals and sepals. By separating the shading process on concave and convex parts, it becomes clear how forms affect light and shadow. Hence, the drawing will be more accurate and logical.
Now refine the gradation of the shadows, refine the clean edges, and deepen the dark shadows. Using an eraser and a light touch, recover reflected light, then add any finishing touches.
