Does your art have to match? No it does not, you are not one-dimensional neither should your art be. You can hang a Renoir next to a botanical watercolor, or a Dali next to a charcoal sketch.
Perhaps you like Photographic art. The photo of the Old shoes just pulls me in. You can check it out on Random Oasis Photography
How do you frame a photo or piece of art. My suggestion take the art with you. Lay the frame over it does it enhance the art? Perhaps matting?
I have three small painting listed with Mediterranean Seaside setting. I am showing one piece here with three different styles of frame. Which of these frames would you prefer?
