Some people like the shadings in this draw, so I posted a Tutorial of it to illustrate the steps I took.
First you search for a reference, when you did that you'll make the lineart. Ofcours it can't look exactly the same. unless you're born with super-copy-powers :D but you try (ofcours) to make it look like eachother, i tried my hardest XD
After that you put your lineart to multiply, and draw in a new layer under the lineart the background. it's easier to name your layers. for instand, name your lineart layer, Lineart, and your background layer, Background ect. you can be as creative with the background as you want, no one's stopping you :)
After coloring the background, you can start with their skin (in a new layer), I didn't save the skin how it looked like when i didn't start the details with airbrush, so you can't see how i did the skin, but i did color it with the normal line-tool and detailed it with airbrush. also add the details in their faces in this layer.
After you did the skin, make a new layer and call it, Hair. I did the same thing with the skin as the with the Hair. And cloths. Color the main colors with the linetool, and finish it of with airbrush. the hair took some time, especially Sasuke's hair.
You guys probably know what comes next, Make a new layer and call it Clothes. i do have a example of how i did the clothes with the main colors and how i used aibrush on it :) though its only sasuke's shirt.. a part of it D: i have naruto too, but not with the main colors of how i shade his clothes.
Now you're finished. you can be happy, sad, angry, strange about the finished draw :) thankew for looking at this boring turotial :D and don't forget, Sasunaru is ♥ :D (and no i didn't draw this Jiraiya, i thought it was funny to add it here :D..i know random) :D
