In #15 the speech bubble probably gets a bit lost in the word pocketbook, maybe some cut-out?
I like the functionalism of #13 and #14, but I'm not sure if the icons are a little too mechanical - if we removed the words they don't really communicate that they're speech bubbles and books - great idea though! Perhaps there's some way we could develop this?
It might be worth considering that the logos have to work white out of black (WOB) - this means that the red spot colour should not run next to black (because in a WOB situation both colours would become white)
As a result #22 probably wouldn't work for us yet?
