This turned out just gorgeous! I used to play around with oil pastels in school, but haven't touched them since... they were always fun to use, but can also be very challenging - you were able to achieve such beautifully blended features on her face, and great details on the costume, it shows that you've had lots of practice.
While it's not photo-realistic, you can definitely see who it is, and you've captured her likeness beautifully. I like the choice you made to use such vibrancy in the colors. Can't wait to see the next pastel painting!
