Nice pose Marty. The silk on the ground is very well-lit. I would be careful not to let my hairlight overpower my main light (as on her right shoulder) and ensure that the face is well-lit and the eyes have visible catchlights. Keep shooting!
Hi Marty, try this: If you have 4 lights, it doesn't mean you have to use them. I would say this is a bit over-lit. Just use 1 softbox -- the biggest one you have and move it in as close as you can. Us a backlight for seperation from the background and use your reflector to fill in the shadows.
If you feel the need to use two softboxes make sure you can turn one up and one down -- one light needs to be dominant and the other is for fill. Remember: The farther you move your light away from your subject, the harsher the light becomes. Try to work your light into a 3:1 ratio (for myself I like it a little more dramatic than that). Good luck -- Tony
