Here's my entry
They really didn't have a lot of rules about what you could enter. So I went with an example of traditional photography instead of one of my photomanipulations because I didn't want to get disqualified because they weren't specific about what you could enter.
Congrats Mnguyen8097 on making it as a finalist. The only thing I can imagine for the color difference is if you sent them a jpeg that wasn't sRGB. Sometimes if you don't have sRGB it will appear differently on the web with colors being less vibrant and looking darker and more washed out. Besides that, I don't know why'd they'd have a different color unless they accidentally changed the color space when they added their own logo to the image. It doesn't look like they changed my color space, but who knows.
