Thanks for the praise guys, especially from Mrs Invicta!

Regarding the gold work, here's the way I did it
All the paints used were from the Vallejo Game Color range (co-incidence really as I use a mix of makes)
I started with a black undercoat
Next was a layer of Tinny Tin, being careful to leave some black showing at the joints
Follow that with Glorious Gold & then Polished Gold, both slightly thinned to allow the previous colour to show through at the edges
Finally I picked out the highlights with a 50/50 mix of Polished Gold & Shining Silver
Quite a few steps but it worked out nicely
