Seeking help for lighting this shot.

The lighting doesn’t have to be perfect by any means, these are just for client outreach videos. But I would like to work on my lighting in general, as I feel like it’s my weakest skillset currently. Any and all advice appreciated.

Using a book light with a diffuser panel to my right as the key, a literal desk lamp to my left as the fill, and a little rinkydinky LED panel designed for videoconferencing as the backlight/rim light.

Room has no windows so natural light isn’t an option unfortunately.
