Think about creating a walkway in a garden,

a path made with pebbles. Instead of dumping the bag of rocks into the path and pushing them around with a rake, you move them around pebble by pebble. Well, clearly I cannot do that — am not that crazy. But the changes to the picture seem like shifting pebbles around in a path.
I posted this before, and I have worked on it a little more. This is the larger version of the motif. It’s on blue paper. The other smaller one is on brown paper. I wonder if the changes are even visible to the spectator. More increments are necessary, I think, before the changes really take hold. I’m not ready to let this go, and yet the differences between where it is now and where it needs to be are slight.
I had posted details of the other drawing. Here are a few of the same passages from this drawing.

It corresponds to this detail from the other version (below).

And the central portion of the large picture:

And the slightly smaller one (below):

The one helps me think about the other.
One quality I love about pastel (both oil pastel and dry pastel) is the ease with which you can drag color over top of existing layers. The slight change in the surface, like rearranging pebbles in a garden path, makes the thing more tactile — and (somehow) seems (to me) to make it more real.
A garden scene of floating world with trees above and clouds below is not different from a herd of koi seen rushing through the water, the planes of water shifting as the koi move through. One is like the other. I often think that I am continually painting the same picture over and over, whether it is koi or landscape or flowers or something else.

Why is a koi not just like a cloud?
