Creative Commons Cheat Sheet

Ok, so I thought I would try my hand at remixing by making a Creative Commons Cheat Sheet that everyone could use to introduce CC to others. Please give me feedback on anything I can improve on it.

Also I have a question: I am working on a citation curriculum at the moment and I am thinking about adding this cheat sheet to it as a supplemental. The graphics I used have a CC BY-SA license. I assume that mean the Creative Commons Cheat Sheet needs to have the same license, but would that mean my entire project would as well? Or is it ok for part of a project to have one license and another part of it to have a different license?
