Those thigh-high high-heeled things don't work for me
Otherwise, this is a pretty good miniature. I can't decide if her facial expression is "whoops I guess I destroyed that" or "what shall I destroy next?" Maybe she's in transition between those thoughts. Her body is believable, not exaggerated.
The gun is ridiculously large, but I can assume that it has some kind of gravitic compensator to reduce its apparent weight to something a human can carry.
That apparently powered exo-skeleton isn't connected to the legs, so she's probably straining her back every time she uses the arm. Hope the gravitic compensator on the gun doesn't fail, or she'll end up with a compressed spinal disk.
Aside from that, the gun looks like it shoots slugs, but doesn't provide a shoulder stock, so recoil is going to make it totally unmanageable.
