The Pendant

This is an absolutely stunning image. The light flare in the model's hair is perfect, giving her an almost "holy" quality. The dress is a good colour and e reacts well to the lighting. The pendant is a nice touch and adds an extra layer of depth to what may otherwise have been an unremarkable image.

The blurring of the background also allows you to stand out more against the background, a good technique to be using. The red highlights in your hair perhaps could have been a touch lighter or darker (possibly the dress instead) as it can be a bit of a guess as to where the hair stops and the dress starts - unless this was your intention in which case well done.
The model's face, whilst lovely, could've had a slightly more confident expression. This image gives the impression of being slightly surprised by something behind the camera.

Overall a very good photo, and one you should be proud of.
