Are you looking to have your logo design define your brand?
It is a popular misconception that your logo design defines your brand. Quite honestly this idea is very far from the truth. Your logo does, in fact represent you, be it good bad or indifferent.
A client may come to a graphic design company and tell them how they envision their logo and how they want it to represent their business. While this can be done visually with some success, that is where it stops.
