I agree, the lighting is a little off, imo, and lighting is a lot more important than people realize and also is a really subtle and difficult thing to get right. There are some seemingly obvious ideas but then tons of non-obvious that are missed. I say that as someone who has lighting as their weak point. I pay a lot of attention to it specifically because it's not my forte.

In this case, I'd say you want a lot more light from multiple directions, which can be done by turning down the hot light, and opening your aperture more. I've always found recording with more light is best (as long as you don't blow out the detail) because you have more freedom to bring it down in post.

Look up some low cost light hacking options, I've made some super janky stuff that worked really well in the past.
