The throne reminds me of Gianlorenzo Bernini's Throne of St. Peter. Could that have been the inspiration? The pillars in the back, the baldacchino over the papal altar Or I may just be seeing things (but if it is, love the symbolism!)
If I were to provide any useful critique, it would be that the Hands are WAY to small, remember, a hand can cover half the face of the individual they belong to. Unless this Queen here suffers from a bone-disease case that only extends to her hands... Nevertheless, the critique aside, it's very well done, beautiful in any regard, + the fact you had patience to make something so detailed in the first place earns you an award.
