I want to get back to my stories, creating comics or illustrated books (something like storyboard).
All this time I was trying to reach a style that I like, and I think I finally found it (not a forever style, but something that I like now).
In this sample, the b&w and colored version of the same image. For shadows, I used a layer layer full filled with grayish blue , then with a soft eraser created the white spots (look at this tutorial:
corel.force.com/learn/articles…?). After, desatured the image to get the b&w. If I want a colored page, simple add the color layer and additional effects layer, if necessary.
