keylight+spill slayer (bias to 65) + alpha matte to make the Light Wrap (I mean, this:

I do not have your SpillSlayer.

But try this

In a composition with your Background and foreground layers
any your key layer if separate ( as that becomes your keying mask.
On the mask layer apply an opacity reduction. ( to suit your eye).

On the foreground layer apply a levels correction effect. set output white ( lower slider display) to set foreground to taste ) set the blacks also to best match your vision of the shot.
Adjust gamma ( middle triangle, upper slider display) to a level where you believe it best serves focusing the audience on the talent.

Hit Ctrl + Alt + y to create an adjustment layer. Rename the layer color correction or CC.
To this you can apply you favorite color correction effect. A photo filter, a gradient anything you like.
Apply an opacity adjustment to the CC layer to best match the look you are going for.

If the result still looks like it has too sharp an edge;
Try one or more;

A. Try adjusting the spill or other edge related settings in your key effect.

B. Try adding a very slight box blur to your keying mask.

C.Try adding a different blend mode.

As always take notes before and after so you know where you made changes and the result. Include what you did or did not like about each change.

You will find the same methods on different footage give different results. Writing down why you think the results are different can add to your understanding of digital imaging in the future.

As a side note;
____________________________________________
Before you start

If the BG and FG footage were not shot with the same camera
or if they are not even the same aspect -etc. Learn how to match grain etc. To make your chroma keyed shots look more like one single shot.

Practicing compositing with the selection tools in Photoshop will help you get a feel for mask edges and the various ways of dealing with them. The refine edge panel and trying all of its settings and modes will show you the way.
