After multiple changes and and refinements, I finally get to this stage. I mostly prefer black line art with cel-shaded rendering in my work, however I make another variation with colored line art, which works better on the darker background; black line art version will stand out more on lighter background, which visually pops out more.
I have them test-printed in A4 size, then get them mounted and evaluate the look and feel. A name can be added into the photo booth, on the top section for this design. Hmmm…I need a model to stand behind the photo booth, a tiny one I believe.
