Well done! If something I would have framed so that the legs of the girl in the second picture would be cut by her knees. Not that I dislike them
but the background/sidewalk gets too sharp and distracting. (Except that I would not, because I would be concentrating on something else. I only realize that kind of things on my computer). Could it be that you are tall and therefore framed the picture from your "usual” point of view?
Note: (Sure, don't crop by the knees. I suppose my English is not precise enough yet... I mean which difference is there between cropping “on”, “at” or “by”? )
