Cartoony, old GW gold style indeed. Perfect, couldn't have done as good myself. Plus the reflections and placement of dark vs light is spot on. What did you use as your base?
I too love looking at Vincent's gold. He is actually a ton of help if you ever PM him, especially if it is regarding SENMM. He does the best SENMM gold in the biz! Did you know he basically started painting and won the Slayet Sword in the same year? He puts a ton of work into a mini tho, 300+ hours.
Add scratches, if you dare, by using your brightest highlight BEFORE pure white and making a small line, then a pure black line underneath. Or in a couple spots make a small dot with the bright then make a half crescent in black around half of the dot. Good way to make holes and scratches, but easy to overdo. They must be super super thin.
