Wow, 2 1/2 years since this was posted, but thought I'd make a couple comments in case you're still around. The works are fabulous!
Describing the work as abstract art is what comes to mind. Would love to see photos of the original works, too.
I can think of several ways to market art like that (and it is VERY marketable) -
- Limited edition prints in a variety of sizes, framed or unframed.
- Downloadable prints - in A4/US letter size for desktop printers
- Greeting cards
