Hi there, I am designing a logo for a client at the moment. He has shown me an existing logo he likes and asked if I can do him one in the same style, but with his company name on. I'm just wondering if I will be infringing on any copyright laws if it looks too similar to the example he has given. How different does an image have to look so that it is not considered to be copying someone else's work? Any advice much appreciated! Thanks!
