Hi Levi,
This product is simply magnificent! As the previous editions and incarnations of this product it just drips with the theme you have chosen. Magic is the best part of rpgs to me and this is at least in the top three magic related products I have ever seen, including the biggest productions.
I have only quickly skimmed it through, but wanted to offer one mistake and one suggestion. The page talking about hearth magic has an error were it says heath. The other thing is about Wyrd element. You have put it up as purely negative effects, but in my meager understanding all kinds of positive effects and protective enchantments are a classic genre too. A witch casting a good luck charm over the departing fellowship etc. I think it would make the product even better.
