Here is my first attempt of human skull and this post is just for the shape and proportions, I am a bit confused about this, therefore, want to know how close I am from real thing. Please comment and let me know the improvemements.

Great job! When I first started to learn ZBrush, my teacher had us learn how to sculpt a skull as well. Doing this will build a good foundation 
Did you only use pictures for reference or do you also have a physical replica?
I am actually following the tutorial of Scott Eaton and laying the foundation for human skull, although I want to know if I can buy a human skull cause I am actually looking for it online from a while but the one I am getting is not that great in quality.
I am using references but I am not keeping it as a blueprint, rather eyeballing it.
