Firstly, I want to thank you for giving my situation a thought even more, a consideration.
Starting, I will answer your question without an AI
Definition
I will define graphic design as the arrangement (or composition) of graphics elements such as shapes, texts, lines, colors, textures, patterns, space, etc., applying the principles of graphics design (hierarchy, alignment, Contrast, Balance, Repetition, etc.,) to form a finished composition that conveys a value and emotion.
What I think it is:
I think that graphic design is a digital skill that can be shaped into a stand alone profession and / or into an associated profession, where it interrelates with other units within a larger system.
What would constitute good graphic design:
A good graphic design would constitute shapes, texts, colors, space, lines, textures and other elements well laid out with the principles of graphics design applied.
What are some of the precepts that form foundation of good design?
Some of the precepts that form foundation for good graphic design are; Hierarchy, Alignment, color Balance, Repetition, Contrast, White Space
Furthermore, the only option I had was to teach myself. I realized that I had passion for Graphic design after working with Microsoft PowerPoint package and using the “morph,” transition to make customized animations.
The urge to grow deeper and master making illustrations both static and motion, without excuses of limitations has brought me to this point.
I am confident that with dedication, continuous practice, and a good mentor, I can rank as a good designer too.
