he looks yorkie to me
as you'll come to find out there isn't a specific "Yorkie look" all our babies look different, and (for the most part) they are all yorkie...
Belle isn't quite a teapot, but she's also not standard, i like her size cuz she can play a little rough and jump around, and i'm not afraid she's going to break... she's pretty sturdy at 8lbs...
once again congrats on your baby...and no matter what he is i'm sure you'll love him nonetheless
