start off with a sketch of what you want to do
make a new layer and create the lashes and lips (will make another tutorial of that some day) draw the dots for the nose as well
create a new layer inbetween the sketch and the lips/lashes. color in with the desired eye color and then darken/ add highlights.
now make a new layer below the one you just made the eyes on. use a darker skin tone and outline where the skin is going to be
fill in with the desired skin color (on the same layer) its okay if you color over the darker lines, you can redraw them later.
now choose a darker skin tone (this will be your shadow) using the water tool create the shadows and nose. make sure to use the blur on the edges!
now choose a lighter skin tone. using the brush tool, create some “light areas” around the eyes and next to the nose.
now blur the light areas. next add some blush (if you want.) make sure the blush is a bit darker than the skin color or it will look strange :0
blur again to even out the blush. Finally, add the whites (on the same layer)
lastly, add some shadows on the whites of the eyes.if you want, you can add dimples, extra shine etc if you want and here you have a basic face yo
