I like the darker tones of the second one. I agree the dark part of the sky needs some work. The section across the top of the image seems to be too straight to be clouds but the whole effect doesn't really look like rain either. I'd keep the darkness there, just tweak it some...make it look more cloud-like or rain-like. I like the position of the shoes and socks now. The socks are a bit bright I think but that should be an easy ambience fix, if so desired. (or make a sunray lighting them up? :o) ) Very nice work! :o)
