So here's the thing with the basic colors blocked in.
Now I can "see" it a bit more clearly. I want to create more "broken" color in some areas - meaning the value of a given area will stay the same but hue will vary a bit. That said, there will still be some value adjustment in a few areas and the basic color in some areas will need to be more specific. For example, the greens are not quite right in the trees: The shifts between the light and shadow areas isn't convincing yet.
I can also see the bands need a bit more work...I think it might be nice to use the shallow ripples at the bottom band to create a "Z" up to the right.
Most of all, I want to experiment with thick and thin paint passages. This is something a painting can do that screens and printed imagery can't mimic successfully. The trick will be not to do it willy-nilly but in a way that communicates space or natural texture.
Tomorrow I'm off to Marceline, MO for a plein air event so I'll have a day away from this and be able to see it with new eyes.
