first time in studio

would like to hear critiques both good and bad

Her right side is a little hot from the side light. That's not my biggest critique, however. There are no catch lights in her irises or pupils, which makes her eyes appear dull and unlively.

Agree with the above that her right side is too hot. Her eyes are cut too far left. You should always leave whites visible on both sides of the iris. Lighting on the back of her hair is good. Not a fan of hands under the chin, but that is a personal preference. focus on her eyes is a bit soft.

Ideally you want your main light to be 45 degrees from the tip of the subject's nose both horizontally and vertically. In this case it appears your main light was too low (resulting in the catchlight at the bottom of her irises) and too much to the left (observe the shadow under her nose; it should be directly under her nose to minimize the shadow). Your modelling light will show you where the shadow falls.

Thanks you all for responding. I would like to know if these issues could be or should be address in post ie adding catchlights, correcting exposure on rightside etc.

While you can add catchlights, etc. in post its always better to get it right in camera. Do you have a light meter?

To me the problem is the catchlight is low on her irises. Almost everything we see/observe is lit from overhead (with catchlights appearing between the 10 o'clock to 2 o'clock position) so anything that varies from that is immediately noticeable.

If you shot raw you should be able to easily adjust the overexposed portion on her right side.

yes the lights were metered , exposure 1/125. f8, iso 100. the catchlights are from a gold reflector held to open up the dark side of her face

Nice portrait, I like the contour and fall-off you got on her left side face. To add my two cents, someone gave me the advice to use a light behind me (me-the-photographer) to shrink the model's pupils and get more iris color to show, I think that could have helped make her eyes prettier here. Especially since she's got a really pretty eye color. Just make sure it doesn't register as ambient based on your camera settings.
