Two things that make me think it could be improved, somehow.
First, the pose can be too hieratic. But maybe you are looking for that effect, in the case you are depicting a very important moment. So it can work like this, as well.
And the other thing is related to materials. They are good, but I cannot understand the golden part in the clothes. I mean the arm and the neck. It seems you are mixing golden clothes and golden wire. They are too similar, maybe some difference in color or glossiness could help.
It’s the only point I see. Otherwise it’s a very good job. Congratulations! Have a nice days!
