Actually, I cheat on these, but not all that much ;-) The mirror is actually pretty far behind her (maybe 6 scale feet), I use a 200mm lens in Poser, which minimizes depth. When I do the "mirrored" view I spin the camera around to the back, and have it look "through" the mirror, then I delete the mirror. Then I might "cheat" a tiny bit for better artistic layout, but it actually is pretty close. Mirrors are just hard to figure!
