So this is where the new signature picture comes from! Hope the last one is connected to something too, as I really like it and would hate to lose it.
This is a pleasant, playful picture, with a most relaxed mood! The easy affection of the two is evident... their friendly "at peace" expressions, the warm mutual embrace, the cute hair-pulling and retaliatory tickle... all speak of an intimate, comfortable relationship. The costuming is entirely effective, too: that sweater pattern is involved but subtle, the sort of detail that bulsters credibility without calling undue attention to itself.
PS: Congratulations HDS! 5000 posts is a record to be proud of!
