According to this Reddit thread, artist is named "aym", at https://weibo.com/u/2861967950

EDIT:
From same source:
VA: Tange Sakura

In her keenly written resume, she proclaimed herself to be an elite among elites; aloof, reticent, and timid. She hates to communicate directly and prefers to do it through SNS; she once served under Sir Griffin as his telecommunications ace. She has poor relationship with MDR, and often gets caught up in internet fights with her. According to MDR, only half of her resume is true.

Ah, one of the least appreciated guns in BF3. Garbage IRL but one of my personal guilty pleasures.

Also loli girl is huge as fuck if we're going by scale.

So...
Is she among the 80% of waifus that got blown up THIS time?

definitely not big on her proportions, she seems more like a fairy than a Tdoll by body proportions
