Thank you for your nice words!
I never said anything about lighting, but it was an overcast but bright day, and a white reflector was used on all of the shots (not the bts). I would still call it natural light, since the light source is the sun
Modified yes! I would generally recommend a reflector for portraits like these, especially closeups. It will lift the shadows and lower the contrast in the face. The reflector might have been a little to close on the last shot though, it takes a little practice to get it just right.
