Hi Ron,
Have you got your camera back, or were these before. If its back, does it focus better?
Anyways, I think you problem may be in not being able to find the subject, the reason for the photo. Your fish, you can get up close, your horses, well, I guess thats pretty much a horse and rider. Landscape tends to be fuzzy ( not in your camera, at least if they've fixed it) but the boundaries are fuzzy, shall I take a photo of the tree, or the forest. One red leaf means autumn, a whole forest of orange trees may mean diseased trees.
When I saw this last photo, I was going to direct you to the guy who took the first two here ;-) then I realised it was the same guy.... The first two, brighter colours, more foreground interest. Both have a horizontal line, the river bank, I would perhaps crop them into a more panoramic view, getting rid of the sky, even. If you make a couple of 'L' shaped masks, or cut some rectangles in card to peer through at the image, you will get the idea. Take 'em with you into the country. Its difficult here on my monitor to give a definitive answer, if ever there is one, and I've enough landscapes of my own to work on. However, for your final image, which is 5.25 inches high on my monitor, crop 0.75 inches from the top, and maybe 2 inches from the bottom. It looks better to me. The twigs to the left are too 'twiggy', distracting, and the fir tree, foreground centre right, does not stand out significantly. Maybe, if that was the subject, then ps may help to bring it out.
I think the problem you have is in seeing the image within the view, imagining the final result. I tend to see great views, and use a wideangle lens, then get an image of a ribbon of hills below a big expanse of boring sky, and a foreground consisting of a big expanse of boring countryside. I have a feeling you thought the the house on the lake would be more prominent. It costs you nothing to play with cropping, quickest using cardboard, I reckon, until you get more or less what you want.
It may help, if you get one or two of those cheap disposable party? cameras (I don't mean a nikon) the sort that you send the whole camera off for processing. I think it would concentrate the mind into composing the image, trying to work out the scene before pressing the button. Whatever you're doing now to try and correct it, and you are not happy, then try something else. The scenary is great, your'e great (at least with fish and horses), just got to mesh the two together somehow.
Best wishes,
Ray
