of your 2 reflection shots I like this one the best, I like the concentric rings from the duck in the water which give foreground interest, this is a good example of using the rule of thirds composition with the duck placed on an intersection of thirds and the sky in the top 3rd to give a good balance to your image, the reflected sky in the lake is very nice and the colours are good, just a shame about the area of sky which has blown, I find using a Graduated ND filter really helps in situations like this as it helps reduce the intensity of the brightness of the sky.
