How to Doodle a Submarine
To doodle a submarine, begin by drawing an egg shape in the middle of your page. Notice how the egg shape is more narrow on the right than it is on the left.
Let’s now doodle our submarine propellers. To doodle these propellers, use straight lines and arc shapes. Pay particular attention to the size of each object in relation to other objects. Try to also make the propeller wings the same size in terms of length and width. This isn’t always easy, so you might need to play around with this.
Let’s now doodle our submarine periscope. To do this, use straight lines and arc shapes. For our doodle, we’re going to exaggerate the size of our periscope to give it a cartoon-like feel. Notice the angle of the periscope and the length of each of the lines.
It’s time now to doodle some windows for our submarine. For this example, we’ll doodle two types of windows. We’ll first doodle the main front window. Use a rounded v-shape for this purpose. For the back windows, we will use ovals. Notice in the example how a smaller oval is drawn within a larger oval. Try and keep the spacing between the circles consistent.
Our submarine is almost done. All we have to do now is add some more fine details and some color. First, let’s add a shadow effect to various areas of our submarine. To do this, use short straight lines. Notice also where this shadow effect was used and how it makes the submarine look more realistic. Next, use straight and curvy lines on the body and window of our submarine. This will give the impression that it’s a reflective surface. You can also use straight and curved lines around the propeller of our submarine. This will give the impression that the propeller is spinning and that the submarine is moving. And finally, give your submarine some needed color. The colors you use are, of course, up to you. Submarines can come in a variety of colors.
