In today’s world, whatever you can do, someone else can do better. So it’s very important to keep track of all new updates and trends because competition never rests. This also applies to project presentation. A designer can no longer present his design by only showing it in a flat digital form, he needs to step up his game and show the client how it will actually look like in real life; because designers may have a wide imagination, but clients don’t (the majority of them at least), which is why we have mockups.
