Off camera flash experiment shots . . . feedback?

Looking for some general feedback on these two images of my daughter I shot this past weekend. Lighting was a speedlight camera left a few feet above her angled down to create a spotlight look. No modifier was used, just bare flash set to 70mm zoom. Flash was in manual, I really don't remember what power level I set it to. Manual exposure settings were used.

My biggest issue with the B&W image is the fact that her left eye is lost in shadows. A second flash camera right would have obviously fixed that, but I feel like I would have lost the spotlight effect I was going for. Perhaps a reflector camera right would have saved her eye from being lost in shadows?

I think these photos are wonderful. Great lighting.

In the color photo, there's a darkness that rises up from the lower right corner that doesn't look natural. The light hitting the floor should be symmetrical.

Also, for me, a #1 rule of B/W photography is that shadows should be completely black. You absolutely nailed it there.

I think these have a great feel and style. I would think the floor would be less distracting however it the light was more controlled for less spill onto the floor. A couple ways to lessen that would be using flags to shape the light, or a grid in a stripbox or softbox to the side, for light going across your daughter instead of down onto her. Then add foamcore on the right to fill the eyes. It is hard to control light with a bare speed light. Another option is getting much closer at lower power, in the same angle you used for more light fall off, using the inverse square law to your advantage. The alternative would be using post processing to darken the floor.

I downloaded the bottom image and played a little, darkened the floor and diffused it, and then tried putting her whole photo-right side in deep contrasting shadow that created a different feel, photo-left side sharp and well exposed, right side in shadows so the right side eye that had too much data lost in shadow to salvage. You certainly have a cute daughter!
