How would I make the white highlights like what you see in the fingernails of this image? I've tried several methods but nothing comes out looking this nice.
Create a white narrow rhombus shape over the nail
Menu Filter > Blur > Gaussian Blur
Duplicate the rhombus and scale it
Duplicate and reposition the small rhombus
Select the three rhombus from each nail, duplicate them, move them to the next nail and rotate them.
