It is already artistic!! You might try using some NIK filters on it. It has lots of choices.
I mean art print like a mezzotint

Check with Mr. Fish. He knows how to do it methinks.
Of course, it could also make a good Gum print with black, sienna and ochre.
Dixon and I are already formulating a plan.
One of the things that could come up is that this looks like a split toned image. Processes vary in their ability to achieve this. As a printer, Dixon may well be able to do this with little trouble or the process could fight you like a tiger, I dunno. This could also be printed on silver photo paper and split toned with silenium and gold toners. I actually have the chemistry on hand to take a shot at it but it is a big job and requires a digital negative so it could turn into a two day project. I mention this to give you an option as I have gone to "photo hell" many times in my adventures with alternative processes.
Ho, ho, I forgot to mention the wonderful working conditions in my "darkroom". Nothing quite like spending a couple of days in a dim hot and humid environment with the trays of "soup" and an ancient transistor radio squeaking away in a desperate attempt at providing distraction.
I have a pretty good idea where I want to go with this one.
Are you thinking about dye sublimation on metal?
