It's a great concept... like you finished the painting by adding Neptune and Pluto.
But maybe it's just me, but those two just don't seem to match Uranus. They are more "curvy and thick" and don't have that soft slender flow like Uranus does. Even the clothes seem tighter and not as flowy... it could be me though.
Either way, I love the idea! And yes, love the scepter. Would have also loved to see one of the ladies on it, like on the mirror.
