There are no golden rules to composition but what you can work on is framing.
framing is the act of what you include and leave from the 'frame', so go back to your pictures study them and think about how a different framing would have improved the shot.
For example shot of the man sitting on the bench is taken from a very low angle - that's not how we generally see people sitting next to us in a park (that perspective is used mostly to show the point of view of a small animal). so, you should have stood up and framed from a higher position to get a more natural prospective.
I know you were using a studio camera for street but its all in good fun and photography like everything thing else takes time.
