CollegeFrog Branding

I really need some feedback on this branding effort. Left is the student's home or pad view, top right a business card and bottom right is the homepage.

I just need some fresh eyes on this. What do you think of the logo, the lockup with the name, the green and yellow color scheme, etc...

Here is the current site for reference www.collegefrog.com I want to do a serious re-branding though.
