when you're taking your photos, try to look at all of the edges of your composition and look at what you are or are not including in the shot. you don't want to randomly cut things out, or include things you dont want. in your case, I would have thought about seeing what it would be like to include the entire lamp post in your second shot, also the entire van and the entire wheel in those other two shots. I'm just learning more about photography right now as well, just got my own first DSLR about a month ago and it's definitely a fun learning experience. that advice - looking at all the edges, i've found has helped me a lot. also the idea like someone else more or less said, the photo should tell a story. I think one of the traps with Instagram and Tumblr photography these days is that people take pictures of literally anything and figure it'll somehow look artsy. I have raised my camera and then lowered it so many times in the last month when I have to tell myself to not be stupid and take pictures of totally random things because i've seen so many friggin photos of random things on social media that I think it'll be cool when it's really not at all and there is nothing actually all that interesting about what I was about to take a photo of.
