Ultraviolet (UV) captures of flowers have high intrinsic value seen from a scientific perspective. Aesthically they are more a mixed bag though, and they usually aren't made just to be pleasing to the eye. They document features of Nature invisible to the human eye and that is in itself sufficient to function as a photo.
This Rudbeckia image manages to combine both scientific accuracy and a pleasing view for the spectators. So well done on both scores, Bob. Is it posted on the ultravioletphotography.com site? I recall you are a member there as well.
Since this is the critique board, I'd like to point out the dark patches of the Rudbeckia ray flowers indicate there is too much red in the overall rendition. Making a "white balance" in UV is tricky as the colours as such are inherently false, but using UV filters that transmit over a wide band of UV, plus balancing the photo against a spectrally "flat" thus UV neutral target to get true false(sic) whites and greys are the recommended steps.
