Too many to C&C individually. I think you have a good basic grasp of how to handle a camera. I am not too keen on the excessively blue renderings. One problem I see is the edges of your compositions--you are cutting things off at the edges of the frames, like in the shot of the shoes, you clipped off the tops of the shoes,and in the street scene with the crowd of people, there is too much space allotted to the buildings at the top,and not quite enough give to the people at the bottom of the frame. Same issue with the pigeon...the pigeon is in a park with people seated on benches behind...okay,got that...but is cutting off the peoples' heads the best way to portray that scene?
Overall, though, I think you show a lot of potential as a street shooter and as an observer of people. The shot of the skateboarder who bit it shows that you have the camera ready to go! Your inclusion of people at the edges of your frames makes me think you have potentially excellent timing. Looking at this sampling of your work, I think you could get really good at this genre.
