Step 10: At the bottom of the head, draw a small, triangular shape for the final strap on the Rainbow Smash unicorn's bridle. Draw a couple of short, curved lines that connect the straps and form the bridle's ring.
Step 11: On the bottom of the head, draw a tiny circle inside a small circle for the bit on Rainbow Smash's bridle. To the right of the bit, draw a small, rectangular shape for the unicorn's lower jaw. At the top, draw a line for the teeth.
Step 12: Darken the outer edges of the initial guides to create the shape of the unicorn head on this Fortnite pickaxe. Don't overlap the shape of Rainbow Smash's bridle as you darken the lines.
Step 13: Use the initial triangular shape on top of the head as a guide to draw Rainbow Smash's unicorn horn. Darken the sides of the guide but make the sides bumpy. Inside the shape, draw a series of short, curved lines to make the spiral on the unicorn horn.
Step 14: Inside the Rainbow Smash pickaxe head, draw a series of zigzag lines to represent fur. On the unicorn's neck, draw four curved lines for a rainbow.
