Such lights really need some diffusion in order to avoid the hot spots - for example, in picture #1, the hot spot centered directly on her left eyebrow.
Otherwise, your poses were very good.
In #2 and #3 the background is a problem in that one could hope for something a little less distracting.
The color balance looks good for everything except her skin tones, which look rather orange. I would guess that the general lighting might be fluorescent, while your lamps are incandescent, with the result being some color balance problems.
