Hi. New here. As for the first shot, it turned out being very good. When I turned on my first two lights, I was desperate for a while

I might have one suggestion though - don't fear the light! For my tastes, it is a bit underexposed. Or put it in other words - a bit of the PP (post processing) would be handy. Not sure what SW do you use, but restoring a bit of a tonality moving few sliders in LR (Lightroom) might do some wonders. Some ppl do use so called dodge & burn techniques, which is nothing more, than just selectively brightening/darkening parts of photo. Sometimes just round/oval vignettes are enough. There is also nice PS (Photoshop) plugin, called Viveza (Nik collection, now owned by Google), which might help here, or on1 software (which we use, that's why I mention it here).
During my workshop, I showed the audience, how even under 3 min edit, might create a visual difference. Here's one of such shots:
- corrected a tonality, increased colors, brushed in some more light light to the face, applied a vignette in the end.
OK, so - just don't worry - there are ppl, who do PP a lot, and hence their images from studio is just half-made material, which is later often turned into something not looking like an original photographs. But I prefer those, who know few bits about the lightning and try to use it effectively. Ideally, it is best to combine both worlds
Cheers,
