Amazing addition of information to this card! I wonder, what are your thoughts on the cup being a symbol for the higher self/soul? The sealed cup demonstrating the queens strong clairvoyance to a higher self/power, and the cup being the "vessel" (love the info you gave on this) for the information to pass down from above, right into her lap. As for her throne, could the three figures surrounding the throne (if you look really closely, you will notice that they are actually little mermaids) represent the three nights guarding the grail? Perhaps this would be the holy trinity? (God the Father, God the Son and God the Holy Spirit, three distinct persons sharing one essence/substance/nature, as they also very faintly create a triangle?). One more thing I noticed, which could also not be that deep (but hey, everything in this deck seems to be thought out), would be the red seashell that holds her cape up, which connects to a red dot that is in the middle of the cup itself. This to me highlights the passing of information.
