Several things: First, this is exceptionally good. Any drawing that could be readily mistaken for a photograph has virtues I could never hope to match. The details in her classes are staggering.
Secondly, I have no idea why, but she looks familiar to me.
Third: she is very pretty, and the baby is cute. (Strangely, it's the baby's ear that most looks like part of a drawing.)
My congratulations on the whole work.
