Here is the step by step process behind the X- Men #19 cover.
I tend to set mid tones and use that as a starting point to go darker and lighter.
Then I set my first step of shadows using a “multiply” layer on top of my basic colors, I also tried to work some of the lightning on the background just to have a quick idea of how I want to whole scene to look.
At this point I started laying the lights just adding a regular layer on top of my shadows but under my pencils. I decided to have two light sources: one coming from the right side as sunlight hitting directly at the characters and the other one coming from the left side as an ambient lighting.
In this image you can see that result on wolverine’s face. I went over the whole image using this process.
Once I polish the whole image I start adding some light effects like fog and the sunlight on the right as well as a couple of highlight on the metal materials. Then I go over the image to do a bit of color correction until I’m completely satisfied with the final result.
