Great shots. First one is spot on with side and rear lighting.no reflections on glasses.metering is spot on too.
More of these images and you might make some money and leave your day job.
That is a sharp lens too.
I opened a studio years ago and ran it and had lots of fun shooting all kinds of people, weddings and home portraits etc.
Keep it up and hope you can keep sending images for us to look at.
Well done H.
