Great first designs! My favorite so far is #2 - clean, modern and the use of speech bubbles adds to the 'statement-like' effect. I do find having the words 'unconventional' and 'speaker' on separate lines disjoints the tag as separate messages. At the same time, I like the use of speech bubbles and see the logic behind placing them where you have! If there is a way you can have both words of the tag on the same line whilst still utilising the speech bubbles in a logical way I'd love to see it.
