Compositionally very good, with a lovely marble sky and distant outline.

But the cows need to be be a little closer and further to the left (where they don't interfere with the trees) and the buttercups a bit thicker on the ground. A bit more sun would also help, which casting a slightly dappled light on the foreground would make this picture perfect.

Perhaps you'd like to have a go at shifting them?

Anudder time. It would take from now until the cows come home.
