Thanks, but as it turned out to be, the major weakpoint of this model are not her feet. Gravity can be a cruel mistress sometimes, and since gravity happens all the time her right arm came off. Could be, because of the printing process (I uploaded the first version of this model horizontally, which could be the reason why the foot is rather stable its "Layers" or whatever you call these, are interlocked with the base, well the arms lets say, was not so lucky. (Bonus Irony: The swords on her back, which are really, REALLY Fragile, are still intact... I have to make those a lot bigger next time :3)
The book you recomended looks pretty fine to me, I do use [
this book] from time to time, works pretty fine as well, but for this certain character I used a superhero reference sheet :3.
But I think for my next Miniature I'll take the games workshop approach of slightly cartoonish/distorted anatomy (bigger head, stronger arms and legs), since those are a) easier to paint and b) a lot more stable.
