Hi I'd like a bit of advice please. I recently designed a logo for a friend of mine who is starting up a business. He was really happy with the work and so I sent him over the final logo etc. However I recently went on his website and realised he has changed my logo. (into something which quite frankly looks horrendous-3D rendering, gradients and other awful things) I'm quite annoyed about this as he has basically butchered my idea... I have expressed from a graphic designers point of view reasons why I don't think him changing the logo works, but he isn't paying any attention to it. I'm not really happy about him using my work in this way? Can he do what he wants to my work? Ideally I'd like withdraw my logo if hes using it in this way-or should I just admit defeat and just leave it? Im fresh out of uni so not sure where I stand with issues like this so any advice would be much appreciated. Thanks.
