I am working on a painting at the moment that is 12"x12" which includes an image of my wife sitting on an outdoor deck with a lot of scenery around her and behind her, meaning, it's not a portrait, per se, rather it's a scene she happens to be in. I am struggling so much right now with achieving a likeness in her face, which, on the painting is only around an inch in diameter. Also complicating things is the fact that I've never done a portrait before so achieving likeness in a face is something I've never attempted. I feel pretty good about everything else in the painting in terms of the realism, including accurately representing her body, but can't seem to get her face anywhere near what she looks like. Any tips on achieving likeness in a face that small on the canvas?
