Not to sidetrack from the Queen of Swords discussion (the original picture is lovely, and its transformation into the card is quite perfect), but I've been thinking about the Tower.
(Thank you for sharing it!)
I can see where it being too dark may be an issue, though that didn't bother me. However, it does appear too static, and the Tower is one of least static cards.
I was really thinking of something along the lines of the end tableau in "Fall of the House of Usher," and to see it without even a crack surprised me.
Not that there has to be a crack, I suppose, but there's such brooding intensity to the card, it becomes almost introspective, like it relies too much on the reader's reaction to get the point of the Tower across.
Am I making sense? I feel like I'm meanering around what I'm trying to say.
