Speak to the gaming industry people. Ask them what they might be looking for and that you want to get into the industry doing whatever job there's an opening for.

Learn your craft and as much as you can about picture making. 3D is a little different in practice while the game is running. Compositions shift around all the time. But when you show your work, make sure they can tell what your level of participation is. So if you're doing models, show the model on its own. And you can also put it in context for drama. That shows you can think it through the entire process. But the most important thing is showing skill at a particular task. They hire based on a specialty, at least until you work your way up to leadership roles.

You NEVER want to come in seeking a job looking like you want the job of the person hiring you. NEVER.

You are going to start small. Once you land a job you will learn the other things involved and can work your interests from inside the organization. But if you are starting out, you're a blank canvas that the people who are putting together a team will be looking at to see if you will do what they tell you to do. Show you're flexible and want to learn to do the job they need doing following their vision. As you build their confidence, your creativity will be called in to play more.

Meanwhile, learn your craft. Read about the business. Go to conventions. Make contacts. Be YOUNG. There is no substitute. When you're young you are not a threat. You are golden. Take advantage of the one major asset you have going for you because you cannot make yourself a blank canvas later in life. Or it's harder.

Good luck. Get famous in time. Hide your appetite for fame. Keep it. But don't scare off your job prospects by broadcasting that you will be trouble to work with as you feed your ego. Play it low key.
