Thanks for the good words guys, I'm really glad that you like the final result.
The setup for the first image was:
One 430EX outside on the balcony gelled with full CTO aimed at the back of my model and going through the curtain. Then my key light was mounted on a large softbox right of the camera and almost at the same level as the camera angle, all because of the hat. Then I had a fill light right under, between my camera and the model, firing through one rounded large/medium reflector holder( I think the name of it was 1 in 8 or 1 in 4 reflector). And the last light here was another flash on the model right and slightly behind her aiming and bouncing light from the wall, I gelled this flash in magenta as I wanted to create more natural ambient look.
For the second image I just replaced the large softbox with medium size beauty dish and also placed 1/2 stop cto gel then I took the light from the balcony and placed on the couch where my model was sitting and I also replaced the CTO with full blue gel. For this flash I used the same large softbox but without the diffusers I just bounced the flash light from the inner material of the softbox which was kind of silver reflective surface. Then I balanced that blue light with this very same magenta flash from the previous setup so this two flashes, the magenta and the blue one where the lights for my environment. I used the same way for my fill light from the first image, here I also need to adjust my shutter speed settings and alter the flashes power output as I was aiming at creating completely different mood and look.
I hope I was helpful with something
Thanks.
Nik.
