Instinctually you will most likely guide the project to your personal style, but you should definitely consider your target audiences’ preferences first (if the target audience is indeed a third party). Our challenge will always be to find a good balance between both. Lets take for example, you, being a hip young guy or gal, while the project’s target audience is a much older crowd... You might prefer a more modern, urban or dynamic look, while they might prefer a more conservative one.
