Thanks for posting the other compositions! It is nice to be able to see the same tree in different contexts.
In the original composition, the repetition of tall and narrow forms reminded me a little of Display III---the one with the gingko. It's rather like a "motif" that gains strength (and maybe meaning) with each repetition.
I rather like the high, dramatic placement of the scroll, maybe just because no other display uses the height of the scroll to create the same effect. For me, the vertical elements and the dramatic height of this display evokes a lot of energy--- I can almost hear that waterfall in the distance. I'm not sure that any of the other displays has quite the same effect. I appreciate this display for it's unique viewpoint.
The other two compositions don't have quite the same sense of drama, but they have other qualities to recommend them: What I like best about these two compositions is the placement of the kusamono. I'm aware of the different planes of the foreground, middleground and background. The depth of the tokonoma is used masterfully.
The placement of the scroll in these alternative compositions is strikingly different. I don't get the same vertical impact. At it's worst, it almost seems like many of the others displays. (I hope the artist who worked on these two contrasting views doesn't take this the wrong way.) I might move the scroll a little to the left, but this is just a matter of personal taste and nitpicking. I agree with Yamadori's assessment that the display was transformed: it is much more tranquil, serene. It doesn't have the same movement and energy of the original display. The choice of lower, wider kusamono also contributes to this effect. Things are much more subdued, serene.
