Its all about lighting. 99% of the images I see have direct light lighting.. ie.. direct light from a window or a flash. This does not show the picture in the best light ( sorry about the pun) You should use diffused lighting.. think of a cloudy day and there is light but no shadows. A flash with a small cheap soft box ( diffuser) and some white cardboard on the sides as reflectors will cast an even light. You can play with the white cardboard or use black to decide if you want surface texture or not. The white will reflect and fill in the texture to a degree.. the black absorbs the light and you get a small amount of shadowing ( edge lighting). This is really tricky to do with an smartphone but with 5K LED light lighting, you can fake it pretty well. If all you have is a bright window, a clear shower curtin will diffuse light as will tracing paper taped over the glass. Or on a bright day, go under the patio in the light shade and fake it 🙂 Keep in mind, if you too close, you may cast a shadow yourself .. so don't be afraid to zoom in a bit and stand back. ! This image was taken on my iPhone using indirect light and a white coated canvas I had handy to be the reflector [https://imgur.com/gallery/HHnjnta]
