Sorry for the delayed answer, but curly's edit covers all I was trying to say. Because of the light source is in front of the character, the hood wouldn't actually get any highlighted areas if the shape remained the same, so to emphasize brighter parts on the hood it would be necessary to enlarge the rim around the darkened face to be wide enough to show brighter clusters on the frontal area, which is exactly what curly did.
Your previous attempt also have some noticeable banding on the left side of the hood, try to avoid sandwiching many layers layers of different shades with only a single pixel between each of the shades, that is what is called banding, and is generally considered a malpractice.
Now, you really should try to make it on your own following the guide lines from the edits, good luck.
