Added the text and changed some colors:

Adventure time is hilarious, I thought it was for adults like Ren and Stimpy but... less graphic, until I saw six Nick jr. commercials and realized I was watching a children's show.

I definitely got the references right away, so that's good. I'd go with using colors as opposed to halftones though, did you run this through a filter or do you intend for it to have that look?

As for the type, I think that red kind of pulls away from the rest of the design, even though that's the style of Banjo Kazooie, I think you should stick with the look and feel of the other colors.
