I don't think there's anything wrong with the settings. It's difficult to tell if it's sharp because the forum messes with the sharpness (blurs it a bit) when you upload as an attachment. So whilst this image looks a little fudgy, I suspect the original is good. Focus appears to be on the eyes, and I don't think your aperture choice has made much of a difference. Presumably your model wasn't swinging the glass around and you used a reasonably fast shutter.
For me, the lighting is a bit harsh, but you've gone with a white background so the brighter light isn't so forceful Might be worth just backing the lights off a bit (distance wise) to soften the shadows and reduce the glare. Angled collar bone to the camera and towards the glass is a really nice touch, and I do think the glass adds a nice balance.
I think this is a really good effort if you're not used to this sort of photography. Be wary of hands under chins as they can squash the jaw. On an older model that would not be a good look

Allowing the pedant out for a sec, I'd lose the tiny triangle of light on the bottom edge in the middle, either with a crop or more likely with a blob of black paint. The slash of skin to the (camera) left of the chin-prop-hand is slightly unbalancing. I'd probably have directed the model to move their supporting hand a bit to the (camera) right so their chin was a bit more central on the palm. Lift the head a tad and just rotate it half an inch to either hide or reveal the ear (camera) right. Of course, if this was a selfie that's all moot
Sorry for going on, I just think it's a really good portrait and with some really minor tweaks, could be great.
As to the film... Breakfast at Tiffany's?
