Here is the PSD of the first page in this mini comic. One thing that may be a bit weird at first in this PSD is that the gold also gets its own SSS (Sub Surface Scattering) layer. As a metal it of course doesn't actually have this effect in a noticeable way at room temperature, but I find adding this effect to any warm metals makes them feel less.... dead.
And since gold will be very close to our characters here, I'd rather it look more lively and warm, and this greatly helps with that.
