Grab your pencils, warm up your wrist, and let’s make a cartoon fish that actually looks like it wants to swim off the page. First, collect a few simple tools: a soft pencil (2B), an eraser, a fineliner or pen for inking, and some colored pencils or digital brushes. If you want inspiration, take a peek at '
Finding Nemo' or 'Spongebob SquarePants' to see how different artists exaggerate eye size, mouth shapes, and fin placement for personality.
Start with the silhouette. Draw a big oval or teardrop for
the body — this is the shape that reads at a glance, so exaggerate it to suit character: chubby for cute, long and sleek for sly. Add a guideline for the face where the eye will sit. Sketch a simple circle for the eye, then a smaller circle for the pupil; placing the eye high and forward makes the fish look innocent, while back and squinty gives it attitude. Draw a smiling or grumpy mouth, experiment with teeth or puckered lips. For fins and tail, use flowing, curved shapes — think of them like ribbons. Keep the pectoral fins close to the head for a playful look.
Once the sketch feels right, refine lines and add small details: gill slits, cheek highlights, scale patterns (you don’t need to draw every scale; suggest texture with a few curved rows), and bubbles for motion. Ink with confident lines — vary line weight so the head or foreground has thicker lines. Color with flat, bold tones first, then add simple shading under the belly and behind fins to suggest volume. Finish with a bright highlight in the eye and maybe a splash background. Practice drawing the same fish in different poses and expressions — that’s where the personality really comes alive. I love watching mine evolve across a sketchbook page.
