I think that you should re-write your profile overview, because it doesn't say anything special about you (read more here). Also, you've hardly got anything in your portfolio; as a graphic designer, your portfolio is the most important part of your profile.
I would also advise raising your prices because your work history shows that you've been working almost for free. It says that your hourly rate is $15, but you've been doing logos for $5, which makes me think that you must really be earning something like $2 an hour. This will put off good clients because they'll think that if you're that cheap, maybe you're inexperienced or not good at what you do.
