As some of you may remember, Mystwing breathes out a wispy smoke from his nostrils when he's happy.
Another one of Mystwing's quirks is that he loves having his picture taken, this is a quirk because he is usually more reserved and uptight (in public, at least), if someone asks for a picture, he very frequently forgets himself.
So he seems pretty happy about getting to pose for a camera right after a light work-out, don't you think?
