A very creditable first shoot. I hope that there will be more pictures, as Paul suggests. However, it's important not to rush - you don't want to end up with a dozen frames of each pose, each with the same little flaw that you should have spotted, but didn't. It is hard to get the balance right, especially if you've hired both model and studio!
A lovely model. Nicely styled, with the rose giving Lou something to concentrate on. And a good move to go for a dark background, which can be burned in at the edges to conceal a multitude of background clutter...
A couple of thoughts, though.
There's a lot of light on Lou's face, and on her calves: I'd aim to light them less - the same sort of level as her thighs and bottom, perhaps.
The folded hand are concealing what are, judging from her thumb, lovely nails on the end of elegant fingers - one of the arts of posing is to make sure that fingers and toes are displayed well, and not bunched up. Keep a lookout for this with less experienced models, and be prepared to demonstrate with a few gestures that would be the envy of a Regency dandy. 'Deed you should, Sir!
I think you've processed her face quite a lot. She's beautiful - and while there's a school of thought that every woman needs to be put through portrait software, my own feeling is that most women need lighting well, a tweak downwards
on the clarity slider in processing from RAW, and some reduced-opacity cloning to deal with temporary marks on the skin. And, importantly, a little dodging of the eyes, to bring out the whiteness of the eyeball, and the colour of the iris. (The light on Lou's eyes is perfect: from the side, it reflects around inside the cornea - the clear cover over the front of the eye - and brings an extra sparkly to the picture. A wise tog told me, around 1980, that you should always focus on the sparkle in the model's eyes, and that's pretty much right!)
You've used your zoom set to a 'standard lens' focal length - working close up to Lou (possibly in a restricted space) has meant that the perspective is pretty aggressive, and her feet are small in relation to her face. If you have room, use 55mm, and move backwards for better perspective.
My mod crops away some of the excess space on either side: just because the camera's sensor is 3x2 doesn't mean that you pictures have to be that way...
Nice work - and I hope to see some really lovely further results form the shoot (and possibly the next few sessions, as well?)
