I like this, in particular the effort to avoid flabby abstractions and the the way you've cut your words down to a spare and lean fighting weight. You can go further. For instance:

Goldens as rich as crops of alfalfa

could become even stronger by losing a couple of those weak beats.

Goldens rich as alfalfa crops.

And here,

Sun, on cue, descends
behind the horizon.

begs the question "Where else is it going to go?"

The thing I'd like to see is for you to develop the images more. Right now, they're mostly static, even when verbs are involved.

this old man skips

baby stars whisper

...moon rises westward

Sun... descends

...waves settle, light blinds

Salted throughout are descriptions of color, but the sense is of ongoing activity that simply continues, unchanging. What are the implications of the images you have chosen? What about that descending sun is going to capture our attention? What is the follow-up? It is in those places that you have an opportunity to open up the range and scope of your poem beyond the immediacy of the moment, where you get to follow the language down whatever paths appear. You do that now in your final three lines, but you could break out of the setting throughout, give the poem multiple layers and meanings.

Not really complaining, because what is here is nicely done. But it's always nice to push the envelop.
