Good design is about getting the message across. Using creativity and commonsense to create a clear, focused message. So that it's easy to understand. So that your message gets across whether it's on the web or in print.
With twenty years of experience in marketing and promotions, I've learned again and again to Keep It Simple. Of course, that doesn't mean it's easy. It takes a lot of hard work to refine ideas into good design and persuasive communications.
Good design is beautiful, fun, sensual and engaging. Good design reflects you and your audience. It's a smart solution. And smart solutions tend to be simple ones.
