The idea part is simple but the visual perception is complex.

What the work of art looks like isn't too important.

In conceptual art the idea or concept is the most important aspect of the work

A work of art may be understood as a conductor from the artist's mind to the viewer's. But it may never reach the viewer, or it may never leave the artist's mind.

Formal art is essentially rational.

What the work of art looks like isn't too important. It has to look like something if it has a physical form. No matter what form it may finally have it must begin with an idea. It is the process of conception and realization with which the artist is concerned.

Your work isn't a high stakes, nail-biting professional challenge. It's a form of play. Lighten up and have fun with it.
