Step 11: Use the original balloon-like shape as a guide to draw Roxas' face. Have the line dip in toward the eye on the right side to create his cheekbone.
Step 12: Darken the lines to create Roxas' neck and draw an extra one on the right side. On the left side of his head, draw a curved line for the ear. Draw a couple of lines within the ear for extra detail.
Step 13: Roxas' hair is quite tricky, so it's divided into seven separate parts. Take your time as you draw it and be patient. Draw a series of four diagonal spikes across Roxas' forehead above his eyes. Pay attention to the length of the spikes and their placement.
Step 14: On the top right side of Roxas' head, draw more spikes, except this time they kind of curve to the left to form a kind of cowlick. Use the top right side of the original balloon shape as a guide to get the placement right.
Step 15: Draw more curved spikes to the left. These spikes curve up more and continue the "movement" of Roxas' cowlick before. Notice how some these spikes stick out of the balloon shape a bit.
