I know the feeling when I heard some twenty years old already working for the biggest game or film studio in the world. But then anyone can improve as long as you want to ,put in the time and effort is all you need, is all about mileage, anyone will be good with 50 thousand hours . I don't know anything about digital till April last year when I first get my Photoshop, I'm not there yet but still learning . Set your goal and start your journey , Good Luck !!
