So this is the original after cropping and even this one seems to have that sharp line from the hill to the sky. Unfortunately this was shot in JPEG and not RAW. Maybe I did over do brightness on the hill but honestly the clouds do throw it off. It was about 2 or 3 pm with the sun behind me and a storm moving in from behind the hill so that does make it look odd and that is why I wanted to make some changes to it. What I was really going for was to change the time and make it look like sunset. I really cranked up the vibrance and saturation to really bring out the red/orange that the original file does not show. The tutorial I watched was on how to use gradients to add color to clouds to make it look like sunset. So I used a gradient straight down with Orange and another from the left corner with yellow to add the sunset colors. I may go all the way back to the original again and start over. Once I saw the tutorial I went back to the edited Photoshop file to put in those gradients and don't know all the other changes made to the file (I now know how to use layers)
