Very nice, Richard. If you're willing to spend more time on this.... did you alter the index of the reflectivity index of the sword to a 'steel' index? Perhaps an extra RT reflection might do wonders, maybe at 50%. And I would throw some 'dirt' over the objects (PF world scale), to mimic small patches of dirt, dust, dents, etc.
The coins may need a little golden glow (luminance), and RT reflection as well.
