Thanks. Yes, two models in one session

It was the group decision that we don't use a softbox.  One flash with no modifier on portable 120 V battery pack.  The fill light is definitely too hard.

So I shot the #1 w/o the light. 

I set aperture at F8 to capture the sun flares in #2, and #3.  That was a wrong setting because too much background.   

Now I see the #4's cloth issue.  wasn't paying too much attention at the time. 

Again, thank you for your comments. 

There are sooooooo many young girls want to be a model.  As long as you are willing to pay $$, you could shoot them everyday.
