Here's your design with finishing effects, along with a couple of closeups. Aside from the many metallic effects and drop shadows, there's a couple of other aspects worthy of note. The Irish flag has a rough texture that indicates some wear and tear, which also serves to mute the colors. This allows the harp to stand out; the harp's drop shadow is exaggerated to lift it further off the background. The badge's gold trim, and the top banner also have stressed textures, but the harp and clover have remained smooth. The delicate shapes of these two elements do not hold a stress texture well, and the smoothness maintains their elegant contours. The tartan background now exhibits random shadows and highlights.
The previous, unfinished version is posted at the bottom.
