You know something that occurred to me, I went back and watched your video again and compared to the images you posted. A lot of my critique about things being cut off in weird ways may not apply to your actual photos. The video format you chose is doing that. So the tips of buildings and some of the other things I mentioned were probably not that much of an issue. The video just made them look that way because the video is cropping your images in unfavorable ways.
The edits I made were made in lightroomCC and for the most part were simply leveling the horizon, dropping the highlights, raising the shadows, adding a touch of contrast and clarity, I changed the white balance a bit too the cooler side then bumped saturation just a smidgen to pop the colors. I sharpened the over all image then increased luminescence a bit to smooth out the grain.
For the little sheep I added some cropping to give them a stronger presence and added a radial filter right over the sheep to brighten them up and help to draw the eye inward on them as well as add some details back to the black face sheep. This may seem like a lot and maybe it is but after you spend some time in lightroom or any other photo editing software for that matter you start to develop a work flow and learn what works in certain situations. All these images seemed to be taken on the same day with similar lighting so I was able to spend about 5 minutes adding some basic edits to one image then just told lightroom to apply those same setting to the other two images then took a couple more minutes to add a few changes that were just specific to the individual image like leveling the horizon, cropping, and adding the radial filter.
Im still learning post editing software myself. And there are probably others here that could have done 10x better with less. These images were in jpeg format but with the raw file I think a lot more could have been done with the sky to tease out more detail in the clouds and I think some other elements could have been pushed further without making the photo look too unnatural. Some will probably say the edits I put on your images are to the unrealistic side and I would agree but that is my style and my own self expression that comes out when I want to help express the way an image makes me feel. The wannabe painter in me if you will. The edits I made to the sheep "to me" express the playful and youthful emotion your photo made me feel. So while the sky may seem too fluffy and blue an the sheep a bit to bright I felt that it gave the the image of more child like, happy and youthful presence.
This is one of the things I love about photography. Sure its awesome when you can nail a photo in camera and some are really good at that. I imagine as a photographer becomes more experienced and well connected with their gear this becomes easier to do. I cant tell you how many of my own images were just so so at best and once I added some of my post work they became one of my favorite pieces. I dont think post editing in unethical, I simply think is just another medium to explore in the world of photography.
