Step 6: Inside the penguin's body, draw a curved line similar to a long letter U as a guide for the penguin's flipper.
Step 7: Below the penguin's body, draw two angled lines similar to the letter L as a guide for the feet.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
Step 8: Draw the penguin's eye as a tiny circle right above the horizontal line. Draw a smaller circle inside and shade it in for the pupil. Draw a few lines around it for extra detail.
Step 9: Using the triangle as a guide, draw the penguin's beak. Curve the end of the beak down a little. The base of the beak goes in toward the penguin's head. Draw another line in the middle for the actual mouth.
