-tbh this was easy lol - how I do lighting! 1. Create multiply layer (IF you want, put it as a clipping mask over ur character to make it easier) 2. Color your character with any sort of dark-ish color 3. Make a new layer and set it to add 4. Put highlights/lines at the edge of your character. I usually choose any color but using pale yellow will really make it look heavenly :D
