Image Quality and Quality of Image

This is a shot made in southern Thailand, nearby Krabi, with a rather primitive Canon G9.  The impressionism approach of the image was what I intended, and I took it with the picture with strong effect of grains, and mist.
Size aside, here we see an image of good pictorial quality - at least it is to me, like many pictures with added grains, scratches, vignette........ but on the contrary, conventional measurements about the image qualit has been on the contrast, sharpness, clarity.......
It does not matter to me. A good image is a good image, no matter what.  Does size mattered?  Yes and no. There are uses of larger images, there are uses of smaller images.
