Thanks, but while I agree that the folks in the back rows could use a 
little more brightening than I already gave them, I prefer my version to 
yours.  Perhaps LCE would help too but I didn't know about LCE a couple 
of years ago when this shot was done.  Your landscape bias is showing 
here with your attempt to open up the shadows in the background.  But 
it's a people picture and not a landscape or architectural shot.  In a 
people picture the people are the subject, not the leaves in the tree 
behind them.  Brightening and opening up the background attracts 
attention away from the people which is the opposite of what I want to do.

As to reflectors or continuous lights, the answer is no; at least not in 
any practical sense.  The flash usage in this case is not a fill light 
but the main light.  The light deficit under this tree relative to full 
sun is almost 3 stops and the light level must be brought up to the 
level of full sun or close to it.  A simple reflector couldn't be large 
enough to cover the group and, of course, can't be 100% efficient.  It 
also couldn't see the sun from the position it would need be in due to 
other shade in the vicinity.  Continuous lights would need to be 
extremely powerful and would have color balance problems.

The only significant defect I recognize in the photo is the unnatural 
shadow from the flash and that's the part you haven't solved.  Fixing or 
minimizing that would have required a taller light stand on the main 
light and a big fill flash... neither of which I had with me.  I did 
soften the shadow from the original but it's not bad enough that I'm 
willing to try and remove it in post-processing.
