I have been working both Front-End and Back "A Full Stack" If we may call it.
As Graphic Designer for over 2 decades, I would say being dynamic in terms of design so you can stay track of the trends and be able to adapt clients requirements. But being a Graphic Designer doesn't stops there as I love learning new stuff in this never ending field of digital media.
While Graphics being flat, I liked it to add more depth giving it a dimension with perspective and that's where 3D's comes in, giving it more life specially when you animate them. And this why I love multimedia. I can do modeling to animating them and compositing it into a video but not limit to. And mixing them all and giving some coding turns into an interactive media with the HTML5.
