See the official list:
Only awarded to anyone after each of the 40 top tags has at least 200 questions
We don't fulfill this criterion yet:
our 40th largest tag (4th on page 2 of the tag list) only has 119 questions.

Voted on 600 questions
You've only voted on 361 questions. You have not voted on 600 questions, so you don't qualify for the badge.
The two criteria are linked by and, so it isn't enough to satisfy one of them, you need to satisfy both.
