3 - This does look like good potential. The quality/softness/etc may well be intentional, however a fraction more definition (especially for this size) would definitely have made this better in my opinion. Like the composition and scene, just the top right corner cropped out likely be even better. Could just be the perspective or natural land slope, bt it does seem like it may need a nudge rotate up on the right, not sure. 720 would have helped you in this Challenge, if the quality was there. Toning works well. Like the title.
Good idea. I think a different time of day would have given you better lighting. The horse and rider are lost in shadow and the focus of the overall photo is too soft for me.
