Laurie - your reference i believe is not human. You should make the forehead higher + the side bones from under the eye sockets are too much out. Bring them in. Grays anatomy will also help.
My skeleton project (this may noob challenge) is here.
Connecting the neck - the top 2 vertebrae have special form, kinda complicated. Look up in Grays anatomy(that's where I got mine).
I am in 10th grade, sophomore in high school, but if you don't take me serious, I'll make you.
