Why we search for a good designer or anyone good in any specific field?
We actually want to get inspiration and learn how to do that specific set of things in best possible ways. When it comes in design and beauty I would confidently say that God is the best designer of the world.
Yes! God is the best designer of this world. This is God who created such a beautiful world, wonderful color combinations, full of colors birds and animals, everything and everyone is a different piece of artwork. God created Men and Women and among them given an attraction and amazing beauty to Women, and clearly declared that women is the most vibrant and necessary color of this world.
Every graphic designer of the world is taking inspiration from this beautiful world. So the quality of producing good designs only depends on the absorption and grasping abilities. Whoever has maximum power of absorbing the design and color of nature in his/her thoughts will become the best designer of this world.
There are many and its very difficult to say who is "the best".
Everyone is perfect in one or more aspects. Graphic Designing is a very vast field and there are lot of designers doing their work.
Like me and I think "I am the best Graphic Designer in the world".
