I have two suggestions for improvement.

1) Reorient your light. Your ring light doesn’t light the ring evenly all the way around (neither do most of the commercial ones that are “fed” with a speedlight). In all your pictures, the light is mostly underneath the ring. That puts the bulk of the light slightly under the subject, and this is referred to as “sinister light”, for the unnatural look it gives your subjects. (In “real life” there’s almost always more light into the bottoms of eye sockets than into the tops, because the light comes from above).

2) Add a second light. Your reflector looks like it might do OK with two lights, one on each side. That should really even things out, and leave you with a light distribution that will look good if you go from horizontal to vertical.
