answer:I’m not a photographer, so you can discount what I say if you want. I am an observer, and I know what appeals to me, so perhaps you’ll hear something in what I say. winterscape: too blue, almost grey. Almost flat. Even in a german snow, this seems too muted and too, well, flat. No crispness in this picture. Flowers on hill: same general issue: too flat, too grey. The green is muted. The yellow barely shows its color. Were the ocean and the sky really so similar in color? The problem with both of these two is that there’s no focus, nothing to really look at – just a flat greyish, almost bland scene. The girl: much better. First, there’s a focus – her face. You know what you’re looking at. Second, she has color, contrast. There’s contrast and excitement even without brightness. The colors aren’t boring. Hope this helps/
