Sketch in the basic shape of the curl, spray, foam and base of the wave.
Step 2.Add an extra line running parallel and below the curl line to define the thickness of the lip.
Step 3.Add a flow line starting at the lip and curve it around to suggest roundness of the liquid lip. Continue that same flow line around with a half oval down to the base of the wave to show the concave curve of the wave face.
Step 4.Add the rest of the flow lines. Gradually make each flow line less steep as you move away from the curl, to show the tapered shoulder. Continue the flow lines into the tube to show hollowness.
Step 5.Add simplified spray with thin wispy lines. Add the foam explosion with a series of explosion lines getting bigger as they moving away. Maybe add a foam ball in the tube. Round off the foam at the base of the wave so it won't look flat.
Step 6.Add shading on the wave face with smaller contour lines. Gradually make the lines darker as you get further into the tube. Use crosshatching to add more depth. Lightly shade foam and base of the wave. Maybe shade the sky a little, too.
Pier view.High horizon. Vanishing point left...
View into the tube.Additional variations can be achieved just by moving the horizon line high or low and by moving the vanishing point right or left. Give it a try, experiment...
View out of the tube.A high horizon line and one vanishing point on the left and it's as if your face is against the tube face and you're racing for daylight...
View out of the tube... continued.Move the vanishing point to the right and more of the face becomes visible...
View from a pier.A high horizon line with two vanishing points off to the right and left and it appears as though you're viewing the wave from a pier, looking down on the wave...
Paddler's eye view.Is accomplished by placing the horizon line extremely low. Both vanishing points are located outside of the image border, one to the left and one to the right...
Bird's eye view.This is accomplished by moving the horizon line up and completely off the image. The two vanishing points are positioned way out to the right and left...
Other views.A view looking down the point can also be achieved by moving these ingredients around...
Various ScenesWith perspective you can now create line-up scenes, with multiple waves. It could be a reef pass, a beach break or a point break Add land in the background or in the foreground to give the scene some depth.
See the four sketches below... ...
Variations.Don't forget about hollow waves, freight-trains, slow churning or paper-thin waves. The possibilities are endless...
