Step 10: Draw the guppy fish's tail using the initial shape as a guide. Darken the shape and draw more curves as you go along for a more organic feel. Draw a few lines inside the guppy's tail for structure. Use the shape as a guide for the direction of the lines.

Step 11: Draw the guppy fish's dorsal fin using the initial line as a guide. Just like the guppy's tail, draw more curves and lines for structure.

Step 12: Use a series of wavy lines, draw the guppy's pelvic fins under the body.

Step 13: Darken the remaining lines to create the rest of the body.

Step 14 (optional): For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of them. It's okay to leave some behind. Also re-draw any final sketch lines that you may have accidentally erased.

Final Step (optional):Add some shading to your guppy fish drawing to give it more dimension and volume. Pick the direction of the light source when shading so that the shadows are consistent with it. Vary the pressure on your pencil to get different degrees of tonal value. It's a good idea to use reference for accuracy. And remember to PAUSE the video if you need help along the way.

You can add more value throughout your guppy fish drawing for extra detail. Guppies come in a variety of patterns. You can draw spots, stripes or even add some color. Be creative! If you have a guppy fish, make your drawing look like your guppy. If you like this look, just draw some random dark spots and bars on the tail and dorsal fin using quick, short strokes.
