Here's your design with finishing effects, along with a couple of closeups for detail. The outer ring, harp, and belt details are now a polished metal, with the outer ring showing subtle signs of age and discoloration. The outer lettering has a stronger, embossed red outline. The central blue area has a mottled texture, and the belt body has a leathery texture. The outer badges have a slight colorization relative to their primary colors. The red and blue rings, along with the central elements have been embossed and drop shadows were added where appropriate.
