Help needed with photo painting.

The attached was designed for 36 inch width on canvas. At 100% on screen, you can see the brush strokes and I thought that was what was required. However, the print showed very little brush detail and close in, the print looked like a blurred photo.

Is the scene wrong for a painting?

Even A4 portrait size of a few coloured buoys and a rusty anchor close up looks like a sharp photo, the strokes are lost. I don't want a blobby child of 5 look painting.

What would you suggest?
