On the first one mountains are out of the focus point, the rather simple carving contrast against the complex inlay of the bird on the leaves. And the nunome zogan of the water, that almost seems like reflections, seems like a fair composition to me. The second one is more subtle, more elegant imo, with the way the mountains are done in relief they get a more important role in the composition. You see the mountains raising a bit, some birds on the left, and a little fella on the right, and all this eaten by tha dark patina, that creates a huge sense of a far distance, seems like fog that cover the landscape, and makes you wonder what you can't see. The 3rd one is a different style, is not a kaneieish pictorial approach, but a floral arrangment. It's hard to judge which one has more merit, some might be more complex, others might have more work, and others might have more expression, others might have better composition, all these things must be taken in mind, and it may vary depending on who you ask, some will think that less is more and others will like complexity, i don't know subjetivity and objetive points must be taken in mind or something
