No worries, many a person (self included) has inadvertently (i.e. understood @ no intent @ "cheating") done the same thing in their early participation in the WA/MA. The perspective is that after having been given an assignment, now go shoot something for that assignment ... vs. ... go find something you've already shot that fits the theme.
The spirit of the WA/MA is for us to use the WA/MA as a springboard/fuel to challenge ourselves for our own personal growth ... okay, that and score some votes from our respected fellow FM'ers when we can stack up to the competition. I usually do better at personal growth than I do @ scoring votes, but it's all good.
