The fact that you are good in visualizing doesn't necessary mean that you should ignore fields where visualization is less important. If you will go into areas where visualization is very important, then you'll be surrounded by other people with such skills and you might lose you relative advantage. But in a field where visualization is used less frequency, you could have an advantage in problems where visualization is required, and in most areas of mathematics visualization is useful to some extent.

In any case, as you are in the beginning of your career, you should try to obtain a broad basis rather than specialize in some direction.
