Great work! Sarcastic: love the pace and playfulness, great focus and personality. Keep it directed TO a person you can imagine saying it to IRL, playfully. Really nice! FLIRT: Fun energy and very nice pacing. Love the "oh" discovery variations. Loving the characters enjoyment saying this FLAT: are you holding your mouth/face with your hand the whole time? Just sounds pinched/held and get a little awkward the longer it goes on that way. Nice frustrated affect. A little energy variance will be ok, you certainly have the dissatisfaction aspect down pat!
