Instructions

Numbered graphical instruction on how to draw the foreground.

Step 1. Start with the base of the foreground.


Draw a curved diagonal line from the side to the bottom. Then add shade using the side of your pencil as shown in the picture.

Erase some of the parts to make it more curvy and imperfect. It adds depth to your drawing.

Step 2. Draw the corals.


Look at the reference pictures of how you will draw the different types of corals.

First, add a very light shade of the coral using the side of your pencil. Sketch the outline using irregular rectangle-ish shapes that originate from the center.

Finish your drawing by adding small circles and curves for texture.

To draw this type of coral, make long, narrow, oval-ish shapes that branch out to smaller ones.

Step 3. Add feather-like aquatic plants


The steps on drawing aquatic plants are almost like how you drew the tree coral. The only difference is you use lines instead of narrow oval-ish shapes.

Step 4. Draw different types of fishes.


Drawing fishes is easy since they are variations of shapes for the body, tail, and fins.

You can use the reference picture above to draw different types of fishes to add to your artwork.

Step 6. Draw a shark.


To draw a shark, start with an oval that forks at the end for the tail. Next, add a darker shade on top of the shark. Then, using triangles, draw the top and side fins. Lastly, draw the face and add 5-gill slits.

Step 7. Add the mid-ground.


Draw the base of the mid-ground, which should be less dark than the foreground. Practice drawing all types of corals that we've learned.

You can also add anything that you want, like whales, octopus, and even mermaids!

Step 8. Complete the background.


Draw a very light background of coral reefs and adjust tones and textures to make it more appealing.

You can now color your beautiful drawing. Choose colors that are bright and vibrant. Colors like bright greens, oranges, yellows, reds, and blues will bring life to your drawing.

Tips for art-mazing success:

  • It never needs to be perfect! It's okay whether your lines appear crooked or your shapes do not appear as they should be. Practice is key!
  • Draw any other objects that you want. Let your creativity and imagination shine!
  • You can add a darker value to the small shapes to show depths to your drawings. It will make the main parts of your drawing pop out.
  • You can draw while looking at your computer monitor or print this page to see each step in greater detail.
