I'm undecided on this combination. The dark base seems to bring out the brushstrokes in the gold but it also brings out pops of color in the shimmer that I didn't notice when I used the gold alone. Here's a differently lit shot showing both things at once.
Now that I've looked at these pictures, I'm wondering if Golden Light over a lighter base would be just the thing. Maybe in another month I'll have tried that.
Reminder: my Halloween giveaway closes tomorrow (October 10th) at midnight Eastern US time.
