1. Look at the video relevant to your specialty : 2D-Drawing (2DR), or 2D- Design (2DN), or 3D.
2. Look at the list on this site and think about the ideas in relation to your ideas, so far, about your Concentration. Remember, you do not need to settle in on a Concentration yet. You are in contemplation mode.
3. Finally, think about the strengths of the portfolio and kinds of ideas the video(s) and the list gives you. Consider how they might help you to narrow your focus, even though your focus might be quite different.
