The second dolphin is full of curves as it flexes its body during the leap. Using the basic shapes as a guide, I can draw the general shape well enough. It is then about adjusting the outline until you are satisfied with it. I was still not happy with my drawing at this stage, but it is all right as I can adjust further in pen later.
It is time to flesh out your dolphins. Before you use any colour, use your pen and shade in. I began at the dolphin's right pectoral fin (the one that is poking out from the far side of the body), where I have shaded in heavily by scribbling back and forth in a technique known as crosshatching.
Lighter parts of the body come in various shades and are created by scribbling lightly and while the ink is still wet, using a finger, I gently smudge it along the body. Be careful when smudging, use the finger to direct the ink. A rubber can help mop up any smudge mark that go over the edges of your drawing, but only when freshly wet.
I then go over with a light layer of grey pencil crayon for dark areas and light highlights of yellow for the beak and other lighter patches. The splashes were created by simply scribbling light marks to represent water spray. Shade the tail flukes in after you add the droplets around the tail. Finally, colour the sea around the spray a dark layer of blue mixed in with scribbles of pen and apply the blue as lightly and as less as possible in the splash areas.
There you have it, two leaping dolphins. You can draw other species of dolphin and in other postures using this guide but adjusting the differences to the way you want them to be. I hope you enjoy drawing as much as I do and there will be another How To Draw soon. Good luck with your drawings!
