Very nice Piro and congrats on getting studio space.
Beautiful lighting on these.
My only concerns are with image 3. I feel that the crop and pose you have used makes her thigh look larger than it ideally should (particularly when you compare her legs between images 3 and 4) Her legs in image 4 look long and lean and much more flattering.
If her weight was shifted more to her buttock furthest from the camera this would help to relieve body weight from the thigh closest to the camera, making it appear thinner. Also because we don't see the line of the back of her leg/hamstring it seems like the width of her thigh continues past the low edge of the image, giving the illusion her leg is bigger than it may actually be.
I would have also tried to move her right arm/elbow back a little (closer to the edge of the couch), so we could see the line of her back between the triangle that would be formed with her upper arm, lower arm and torso. I think this might have been more flattering and would have complimented the triangle being made with her left arm.
Care to share your lighting setup for these?
I'm guessing perhaps a beauty dish or large octa with reflector for fill from underneath or side?
Looking forward to seeing more - please keep them coming
