Not at all; Photo 2, in colour, is better (IMO) but two contradictory things happen in it: the colour shot makes the picture-within-picture more interesting because it looks to be an old, classical image and gives the girl a sense of intellectual gravitas because of it; the overall colour is killing the picture for me. I'd work on trying for a more 'natural' overall colour. The b/w just looks flat as a pancake.
Cannes, Shot 1, is not the way you show it. Of course it is, but that's not what I like to remember about it; I'm a sucker for its glamorous image, not the Parisian 'reportage' version which you will find all over Europe.
Shots 3 and 4, the street portraits, are perfectly good for what they are, but they miss the element that makes them different. Without that, they are just 'more of the same', as everyone else with that sort of desire produces.
Shot 5 is just a terrible exposure of two kids on a bike heading for an accident.
Let me stress: this is only personal reaction and, like all other suggestions about another's work, has no value beyond that.
You really want advice? Just do what you want to do and the hell with the rest of the photographic world: it's as confused as everybody else.
