According to the Custom Badge FAQ, proposals need the following to be considered:
- Badge Name (25 characters): This should be a descriptive, and maybe
even fun, name for the badge.
- Badge Class (Bronze, Silver, Gold):
Specify the class for the badge. Remember that gold badges should be
fairly rare!
- Badge Description (200 characters): This should explain
how the badge is acquired.
- Awardable Multiple Times? (Yes or No): You
should indicate whether this badge can be awarded multiple times. Most
of the time, you should default to “Yes”.
- Criteria to Earn: You should
explain how a user would earn this badge. These can be as objective or
subjective as you feel is appropriate for your community.
I've put my suggestions below, but please feel free to propose edits (or entirely new answers if you'd prefer):

1: Thanks to @pinckerman for the rename! I originally suggested "Screenshot Comp Winner", as "Screenshot of the Week Winner" blows past the 25-character limit. Still open to suggestions for other names.
2: Save the Silvers and Golds for win streaks and other "harder" goals
3: I'm assuming both links AND tag links that point to Meta tags are acceptable here. The former is used on multiple badges, and the latter is used for Tag badges, but they point to the main site, not meta. If we can't use tag formatting, a raw link to the meta tag page for screenshot-of-the-week's newest tab would also be acceptable.
4: This covers us for the situation where a submission earns more votes after the winner is announced and the competition is closed. (Note that I thought we could potentially have a separate badge to recognise this special case, as covered by my answer on Meta SE).
