When a design is focused, it instantly becomes good. A good design is effective and efficient in fulfilling its purpose. It relies on as few external factors and inputs as possible, and these are easy to measure and manipulate to achieve an expected other output. The design would also use a lot of contrasted colour pallet within, giving it a balanced end result.
These examples of graphic designs are taken from tumbler.
I like these photos as the colours match in each design, they are also very pleasing to the eyes. I presented two types of graphic design styles, a simple solid colour with a lot of negative space, and a complex geometrical, graphic that has a consistency of shapes, lines and patterns.
