I noticed the angels, but at first I thought they were two moons.
To me there is a difference in how the device is drawn and the rest of the picture. The object is drawn with a finer pen, is rendered with great detail and more importantly is more 'realistic' than anything else.
If you look at the long tradition of Japanese art and even in Manga you will see that when the artist wants to depict something as strange/unusual/dangerous they would depict it in a more realistic manner. So too here.
The Queen is holding something that quite possibly does not belong in her World, and as such requires great concerntration to comprehend it.
The background is interesting too. Its almost like she's going to place the device down on the edge of the cliff! Such a 'trick of perspective' is not unusal in art.
This card also reminds me of an image of "The Temple of the Rosy Cross" by Teophilus Schweighardt Constantiens.
g'night!
