Cloning in some extra canvas area around her, as Lew did in Post #6, really improves the second photo. I see quite a significant difference in the uniform color between shot 1 and shot 2...was that intentional? Not that either uniform color is "bad"...it just seems odd that there is such a big difference.
I do not think the white rug is really a good posing aid for women's basketball shots...just does not seem to be situationally appropriate...
I think the pose of #2 is more "fun" than the static-feeling seated pose of shot #1.
As to umbrella flash and distance...when an umbrella is pulled in really close to a person, the light has VERY steep fall-off from one side of the frame to the other side. In fact, when an umbrella or softbox is pulled in very,very close to a person,even across the short span of the width of a human face, there can be a 1- to 2- f/stop DROP in light intensity, and at the edges of the frame, there can easily be a 4 to 5 f/stop drop off in intensity....so the idea that moving a light very,very close automatically creates "soft" light is not exactly, a 100-percent "given" when the subject is moderately large and the light is positioned very close.
If you're shooting an apple, YES, a close light will give soft lighting that's fairly low-ratio across the width of the subject...if the subject happens to be two people, standing side-by-side, pulling the light in "very close" but off to one side or the other creates HUGE fall-off, while moving the light farther away from the people will create much,much,much more-gradual fall-off and more "even lighting", with an almost-imperceptible fall-off in lighting intensity across the entire width of the frame.
