It is important to get back some peer review of your work. People who do not know you personally can give you a different view of your photos. As I mentioned in my previous post http://www.500px.com is an interesting site to post your work and hear back from total strangers. It is also nice to follow these folks in return and see the quality of their work. This is not a site like flickr were you just post any photos but it is designed to show case some of what you consider to be your best. I would suggest that you at least check out the site for you will get a good idea of what to look for when you are shooting yourself. Not all photos my be of interest to you but it gives you a sense of composition and subject ideas that you may use later.
