Welcome to APUG.
Diversity is good and showing images outside galleries even better. 18 months ago I saw images in a park in Lima, Peru, and everyone was stopping and looking.
3/4 years ago I was asked to put on a 2 day exhibition a a Canal bopat festival, and wow far more visitors in 2 days than I'd have had in a few weeks with the same work in many galleries.
You can only try, under pricing is bad policy and actually leads to fewer sales. A friend had a framing business & gallery, he sold a lot of paintings & prints but at £10-£15 his B&W RC prints didn't sell, once he increased the price to £40+ they began to. (15 years ago so prices have changed).
