Hello David, im no master myself and i hope someone with more insight can offer you a better critic and judgment. But i will try my best from the few tools of understanding i have.
First of all if you are new to this subject and you want to paint portraits i would really suggest to focus a bit more on drawing, construction and anatomy of the face so you can then work your way to beatifull rendered portraits.
Regarding this painting in specific, if you really want to do something more, you can add details and some colours, have some fun and get used to the brushes and paints. Dont be afraid of doing something different from the original. Like the previous user as said, Vermeer is a complex topic with a lot of information to absorb and replicate.
I hope i helped.
Sorry for my English, and keep working, it is very good when you feel your progress!. Good job!.
