Backlighting

So, my assignment for my photography class was to take a picture of something with backlighting and then overexpose. I have been having a hard time finding a subject to photograph. In the afternoon sun my house has backlighting so I went out in the street to take a picture. I could tell a difference when I overexposed the photograph because the house didn't look so darkly shaded. This photo is a big overexposed. However the sky was a bright blue in the correct exposure and it isn't here.
