Gorgeous lighting on that mountain. The grass below sort of approaches pastel. This shot is so nice that you still got a 5+ despite the dark colors!! Given the colorblindness, you are very courageous for taking a stab at this challenge. Way to be in the game ;-)
Cool shot. Those erotion ruts are awesome. There is something wrong with the blue sky though. It looks like maybe you had used a selective color mask in PS and you adjusted the cyan but not the blue. I don't see a real solid connection with pastels, but I suppose the grass near the stream is pastel enough, so I won't dock you. Keep up the good work.
