Thanks everyone!
I neglected to mention that one thing she did was ransack my copy of the CMON Ultimate Painting Guide!! So we can blame CanopicDoll for the NMM. It's a REALLY good thing I didn't know that she was going to attempt NMM, because I would have very foolishly advised her to wait before trying something that advanced! You're right about the light source (the shine should be on the same side, front and back,) but as you say, who cares?
I think one thing that's happening is that she has a very clear mental picture of how she wants the thing to look. That's a huge advantage, I think, because most of the time I sit down to a mini and think "Okay, now what? Hmm... maybe I'll make this bit green or something." I think it was also why she was kind of frustrated and dissatisfied with her progress, but after reading everyones' responses, she's realizing just how good a job she actually did, regardless of how short it may have fallen from her vision. And if this is any indication, it won't take long for her skill to catch up to it!
It's still too early to make a prognosis, but indications are that she's been bitten and may well and truly catch the bug. She's already picked out her next attempt, and claimed half of my Spyglass/Eolith minis for herself! Worse yet, she's been eyeing my airbrush for the past several months...
