The one with clock is great. About the cat... hmmm... great eyes, good colors and nice timing but the rest of that picture is empty, there is nothing intresting on it so even if the eyes are awsome the picture is boring, try to change compositon. About the doll, change angle, now it's looks more like some documentary foto and it's good enaught to look on it for 5s. I've got mixed feelings about the hand, good idea but maybe you should try to change the angle for now the thumb is covering most of the hand.
