They look great. Nice framing and the light looks clean and consistent. My only suggestion would be to perhaps bump up the skin tone in 1, 3 and 4 just a tad.
Ref the lights, are the heads the size of a motorbike battery or just a little bigger and surrounded by big silver reflectors? I remember a guy on another forum talking about some lights by Photolight but I cannot find the thread. I will keep looking, he was after a user manual if I remember correct.
