In the second picture, although I really like the composition, I would try to do something about the feet, somehow they make it seem like there's 'clutter' there, at least to me they seem somewhat distracting, but maybe I'm just paying too much attention to detail, just let me know what you think

, I'm not trying to be negative or anything.
