First of all, thank you, Lindsey!  
Here are Red's thoughts:  "I don't love the font but I don't hate the font either. Maybe it needs to be a bit more Web 2.0."   Colors are a little too bright. Red should be less orangey-more of a blue-red.  And I'm not sure about the green. I was hesitant about that part before I saw your design -- you're helping me decide. 
I don't want the face to be just round.  I want more hair and less face -- and face slimmer.  And not crazy about the lips.
I would love big hipster glasses. 
Stuff I like:
The headphones are really simple. 
I like the speech bubble.  Maybe with a font that feels a bit more contemporary, it would work better. I do like that the font is a bit quirky.
Overall -- you are getting close. I really appreciate your efforts and talent.
