A few things;
2nd - That girl looks like she's shooting left handed, but sighting with her right eye.
See if next time she wants to try shooting right handed...it might be more comfortable!
She is actually right handed and left eye dominant. But if you notice the buttstock actually slants down a bit, if it came straight across her cheek would be in the right place. Trust me I think its right, just looks wrong, then again, i could be wrong.
