I think the muted tones work well here...maybe not from a voting point of view, but rather a lasting impression...they allow the focus to center on the model, and the wonderfully spirit like pose she has...
This is a lovely image. I do like your models pose and the general scene. On the whole I think 6-plus is a comfortable score here. Nonetheless this could have done better but for a few small details. It is clear that a number of commentors rated this very highly indeed.
It seems a number of voters marked you down because they could make out detail in your subject. I'm guessing that they have their monitors better calibrated than either you or I. Always a shame to be marked down for something like that. As has been commented a bit more contrast should have dealt with that. A bit of a rotation to get the horizon horizontal would also have been good.
Looking through the challenge entries it seems that the more vibrant sunset colours did very well. By comparison the tones here are muted. Bumping up a bit of selective saturation on orange and red might have helped. In terms of composition I would have liked to see a space to the left where the model is facing - as it stands I think she is facing out of the frame whch draws my attention away.
I hope my comments help and Good Luck in future Challenges!
The pose here makes the image! I also really like the colour, very evocative and moody. Your composition is also very nice, I expect to see this in the top ten, good luck.
I like the pose and the silhouette of the woman :o) The colors of the picture I don“t like as much... But that is just MHO.... The subject is nice and overall the picture is good... Good luck..
Very nice composition and great pose by your subject. It's a rather small detail but I like the tiny bit of illumination at bottom of the dress. Nice work!
