The whole portfolio screams snapshot.
You should have a theme within any portfolio, this just seems a random collection of what you think are cool shots, and those that are not as cool have had their colours messed with so they look interesting. This just seems like a person with a digital camera with no understanding of the camera conventions.
"If your photos are not good enough, it's because you don't read enough."
What you could have done as an idea was just photograph the people in 'Go Fish' and used all those shots for your portfolio. All I see at the moment is a long distance shot of some guys playing a game, 3 of them with their backs to me. You're not engaging with the subject matter. I could have filled my portfolio with pictures just from those men.
Don't bother with titles by the way otherwise you end up limiting the interpretation of your work. I would start again take an idea and work with it and get 20 shots for your portfolio.
I've been doing a street project since June 2008 and I photograph youths on the street, my portfolio for my Masters degree will soley be made up of this 1 project. Sticking with something over a long term shows you're dedicated to what you're doing, not just running around taking snaps.
Some of my images can be found here:

I started on the street and got to know the youths and now I go home with them and photograph them at home.
