Stories, regardless of the media, are all about ambience, atmosphere, sensation. Plot and meaning are just part of the tools. Consciously or not, authors and artists seek the expression of feeling, as accurately as possible. Most audiences will feel differently and in unexpected ways, close or far away from the original and undefinable purpose.
Ambience can be brought through exquisite sequences of words, sounds, colors and visual shapes, and by the composition and design of a single image or object. This is also called style and each author or artist has a personal one. This uniqueness of style and expression is sometimes called voice.
Comics might be my favorite microphone to convey the ambience of my feelings. It is all immediate, when drawing fast enough. This panel of CHRONOS, without words, was particularly joyful on the making. I really feel the urge to accelerate production. It will happen soon.
