A great start.
My suggestion is that you can do a lot to really crank up the gold on the figure very easlily. I'm going to speak in terms of
GW colors, substitute as you will.
Looks like you have a darker gold on there (shining gold?), that's perfect.
Drybrush with a lighter (burnished I think) gold.
Wash with sepia.
Light drybrush with burnished gold again once the wash is dry.
Mix 50/50 burnished gold and mithril silver & do a very gentle bit of edge highlighting.
The end result can be very nice. The actual model pops a lot more than this photo shows... but you get the idea.
