Well, you have a very striking look so that is awesome.

However, I would like to see what others you have as this one is not exactly right.
You see, you are wearing black and dressed for a theatrical headshot BUT you are smiling so it can't quite be used as such.
It also can't be used as a commercial shot as your smile is quite tight and the clothing is not appropriate for a commercial shot. You need vibrant colors for commercial shots. I hope that makes sense so far.
You also don't look very comfortable, to be honest. I KNOW that there is a better shot out there for you.
This shot would be okay if used as a print ad for a jazz singer or some such. It's not quite there in terms of a headshot. I am also not wild about the angle they shot you from and the styling choices need a little tweaking.
I think green or red on you for a commercial shot and for a theatrical look, I would go for something that didn't focus the attention down your blouse but rather on your eyes.
Like I tell all women, to be sexy, all you need is your eyes. Don't be afraid to rely on that and your inner energy to convey sex appeal. It's all you need- trust that.
Hope this helps.
