Imperfections, you say? Can't say that I see any of those myself. Excellent work! You're going to have a very lovely-looking backpack.
You'll have to remind me...who's Sock Dog again? Is he one of the backgound IFs? If so, then he seems like kind of a random character to include in a main cast ensemble, even for the sake of bulking it up to an even number of stickers...am I right in thinking that these stickers were associated with Season One of Foster's, before Cheese and Goo were introduced to the show?
