After close examination I have Determined that the reason she has a exclamation point in her sentence is because she is not so subtlety hinting us that we are staring at her ,ahem, "curves". This is evidenced by the following; The blush marks under her eyes, which are not visible due to the reddish-orange skin tone. The slightly angry and slightly sarcastic look on her face that we mistook for curiosity. The bold words at the end of her sentence also show exasperation or dramatic-ness. The slightly shy, embarrassed posture of he arms.
I do hope this clears things up a tad for some people.
And on my personal opinion of the art work "Cool & sexy bro, whish I was as good as an artist, like the size and jiggle effects on the rack, and more sexualized pose next time."
