I love how creepy this photo looks. This was at the end of August. I had just got home from school and I was scared! I honestly thought a tornado was coming or something because the wind was blowing SO hard. I even called my mom to tell her to hurry home (even though she was already on her way), because as you can see, we live in a rural area. The [sometimes] abandoned house in this photo is to the right of ours. The different shades of grey in the clouds are great.
I think some enhancing the brightness in the lower part of the photo would really bring out a lot of missed detail while still conveying the sense of foreboding you were going for with the clouds.
