@dml2000
i took a very long look at your render.
And I have just one singe remark .

Please be seated, it is for this render only.
Why use high poly male and female figures for that particular render?

My sugestion would be, use the right tools for the job.
In this case, even posette and dork would have done.
At this focal distance, and as a second argument, from the back, one does not even see the faces?

This would be great with the correct shadows. (would be great with IDL light from the explosion! !
Nice explosion BTW.
Sorry TrekkieGrrrl, was just writing this, as I see your post .
Indeed, hiding unseen parts is another solution.
