Greetings from the Critique Club!
This is a very nice portrait. I like where you were going with the vignette effect, but at the same time it really feels overdone here. That could probably be solved in part by using the effect a bit more subtly, and also by cropping more tightly at the top and bottom - especially at the top. You probably slightly overdid the vignette on her jacket, as there's almost no detail there whatsoever.
Your model is well lit, with the light and the vignette both serving to help keep the viewer's attention on her face. The technicals (exposure, focus, etc.) are good as well.
