It's not at all shabby for a first attempt; nice expression, well caught and nicely processed, esp the mono version.
The framing nearly works; if you're going to have her eccentrically low in the frame to show off the headgear then it would have be nice to have a little more space above it.
I'm not sure whether it's due to processing or exposure but the highlights are pretty much blown; could you recover them from the raw file?
What was the lighting? I'm guessing a single smallish softbox way off to one side, judging by the amount of light on the background. I like the drama of the lighting on the face but it doesn't quite go with the even mid-tone on the background for my taste. I'd have tried to control the light a bit more or got the model further away from the backdrop. A reflector on the shadow side or a touch of frontal fill might have given the image a little more polish and subtlety.
