Oil painting on special paper.
From the family of (rather) new materials developed in the recent years, the paper ready made for oil painting is one of them. It offers new possibilities, both for the painter and the buyer. For you, I'd mention that you can choose the frame you like, even a passe-partout and have it "closer" to the wall you will hang it on. More like you'd hang a poster which to me, it's closer to the style of a modern home. You can also roll it into a tube and, for a while, display something else in that space.
On my website mongraffito.art there's a blog where I describe "Unrealism". It's a term recently coined, to describe the fluid continuation of painting, incorporating abstract art with figurative, realistic one. The direction is vast and several of my unrealist works can be found on the axis between abstract to more realistic (like this one). However it takes a distance from the old tradition of renaissance art, hyper-realistic art and the tendency of some to paint in the old school tradition.
