Bert that is a top image of the Jewel Box, as expected, however if I may be so bold it just hasn't the punch that the name suggests.
It is not your imaging that I question on this object, but mine as well, you have done a fine job.
I too shot this object some nights ago, and as I had never even seen it, I expected as the name suggested that it would be full of punch, so to speak.
Although I did it right, and the processing was OK, I was quite disappointed with the result, and put it down to the lack of experience on my part.
However viewing your image tonight, it still lacks that punch, as the name suggests.
