This is a great photo, I wish I was there. It does need some more contrast - make those blacks blacker. The sun was stationary during your capture so I don't think this meets the challenge.
i think I understand this one - the sun is the non-stationary light source - hence the shot - but it is really not well executed here- too blown out on top 4
This apears to be a day shot with out any aditional light source, but I'm going to give you the benifit of the doubt, however its too contrasty and blown out at the top imo. Good Luck
Details: Use a non-stationary light source (for example, a moving flashlight in your hand) as the primary method of illuminating your subject in a creative manner.
Not only that but the colors are flat, hard to see. The sun is too bright the trees are too dark.
