Master Craftsman Step on Illusion

The theme of this step is illusions: luminosity, iridescence, luster, and transparency. I am attempting luminosity and luster. After 8 attempts, I think I got it. I'm going to call this Moon River.

This is based on an attempt from several years ago:

I decided not to put the trees in, just want to keep it simple and serene. The luster may be a touch too subdued, but I'm going to leave it alone. This piece is to be viewed with calm contemplation (hope the judges agree with that!)

Now I can concentrate on finishing the essay for this step.
