Create a leveling adjustment layer on top of the others and set its values to 235-1-255. That way you'll be able to spot the dust easily.
Also, missing punctuation, bubbles 2, 3, 5 and 6. If you use text boxes instead of point text, those might have been swallowed up (+ sign in the corner of the text box) - be wary of this or use point text.
"What's up?" Make it a bit smaller, you generally want a bit of white space between the bubble border and the text or it'll look cramped.
