That pic is gorgeous.
As for the deeper meaning in artistic works, though, we'll have to agree to disagree (once more ). To say that an artist always is fully aware of anything and everything they put into their work would be attributing a bit too much to their self-awareness, imo. I can't offer such a beautiful example as yours, and I never published much of anything let alone had it reviewed, but I remember one evening at the community college's writing class I took. We had been given the task of writing about an everyday object, and to use second person for the piece (our teacher always had such little challenges). I wrote something (paraphrasing, it's been like 30 years) about blue jeans and how much I loved them, how getting to wear those instead of the skirts of my little-girl time was such a game changer, how much I could do in them now, climbing, riding, sitting without crossing my legs demurely, list goes on, in the style of "when you wore them, you felt that the world was your oyster". When time was up, we read our pieces out loud, and when it was my turn, several of my fellow students stated how this was, behind all that praising blue jeans, a piece about individual freedom and self-expression. I of course protested and told them, no, I really just wanted to say how much I loved blue jeans (I still do, in fact). But on the way home it occurred to me that actually, they had sorta been right about it. When you're in the flow of creativity, you sometimes end up saying more about yourself than you ever intended or even are aware.
To come back on topic, my favourite example when it comes to Moftiss is still this:
These are all female chars of Mr. Moffat's creation, and mind you I found that little collection even *before* Mary Morstan, who in canon is rather unlike her Sherlock incarnation, was turned into yet another black clad femme fatale. Now it's of course perfectly possible that Mr. Moffat is of the honest opinion that it was intricate to the plot that all these roles are of this archetype, and that any potential penchant of his has nothing at all to do with that artistic decision. It just doesn't seem all that objectively likely to me.
