This comes up very dark. I suffered the same fate not long ago because my monitor was calibrated to bright. Maybe you have the same problem. I think it will affect your score as many will not be able to see much.
This photo is a little confusing to me because it seems very dark. I see the Snickers bar, but the rest is kind of a mystery. Maybe it's my monitor? I'm not really sure. It may have been easier to see in black and white.
