Here's your design with finishing effects, and a couple of closeups for detail. We've added metallic emboss and shadowing wherever appropriate. The silver border and slight drop shadow frame the main design nicely. We added a gold piping along the border of the blue areas, which now have a slight texture. The lighting on the central element gives it a rounded, button-like appearance. This element has been softened a bit to smooth the rough edges, only to a point where the image remained fairly sharp.
Scroll down to see the design on a black background, and the earlier version is posted at the very bottom.
