either 1 or 2 - but the font underneath doesn't work for me. And the 'thisisbuble' - try with making the 'is' different (or the 'this' and 'buble'). Lose all the shading and get the rest nailed first!
I like the graphic but the typography needs some work still, too thin, the italicised "is" doesn't work for me and that serif - ok serif may work as Paul said but I think you need a thinner, more refined serif font.
That all sounded really negative (sorry :icon_blushing but it will look really good when the typo is correct
