JSON HELP NEEDED

I have some json i've cobbled together from various places, and it's not working, I am certain it's because of my poor use of the curly and square brackets. I have NO idea how to write json, i'm trying to write it to stipulate a specific theme but failing miserably. 

Please can someone take a look over this and help me with the coding?
