I used ello's free bumPreview tool from this thread to do a quick preview for you

http://stormvisions.com/3DGS/norm2.jpghave to try building a 3D model and getting a normal map of that some day as Drew had mentioned how much better results were given. Anyway it looks good except I think you may have some problem with Moire effect with the wire mesh inlay. If so you may have to just 'mess up' the regularity of the color/lighting/lines of the wire mesh just a little as the regular pattern is what tends to produce this effect.
