Very awesome to read!
A couple things I thought about that you may\may not want to use.
Under the intelligence portion.
Kabuto's "mom" was praised by Danzou as having more intelligence than anyone in the Anbu division.
Orochimaru was interested in Kabuto at a young age (I believe it was because Kabuto was skilled in medical jutsu without being "educated" in the leaf via the academy - that's just more credit to his "mom" and her intelligence\teaching skills)
So I would credit some of Kabuto's intelligence and medical backgrounds\foundations to grow on from her.
But again, quite an awesome read, so much more pleasant then 100% of the stuff I read in the manga discussion and naruto discussion areas!
