Hi Greg,
Sorry about posting my work so late. We had such a busy time preparing for Easter. But now I have more time.
Here is the Dog in contrast pinning.

Happy Easter

Do you still have the Curve file you used for this??  It almost appears that you have reduced the contrast in certain areas of the image.  I'd like to see a screen shot of the curve or post the ACV file for me please...  To save the ACV file click on the "save" button in CM and save the curve to your desktop.  attach it to the posting like any other file and then I can apply your curve to the base image and see what's happening...

It does look like the dog is in need of more contrast. I'll do it again.
Here is the acv file. I hope you can make out what I did.

Okay...Your curve is not really a contrast increase move. 

After looking at it you did adjust the part of the curve that had the right tones for the assignment, but you dropped them down as shown in shot 1.  This lowers the 3/4 tones and makes the image look flat. 

What you want to try to do is create vertical separation between the points you have selected. this would put one point above the diagonal and one point below it.

CM has a feature where you can right click and select "contrast pin"  the trick is to make sure your sample is size is set to 5x5 or larger so you get some separation on the L curve.  See shot 3 for the resulted contrast pin set up.  Points will be set on the curve at the ends of the worm shown. They will have the red dash lines connecting them. Then you put the mouse on the frame curve frame edge so that it is a two headed curved arrow.  on the top of the curve frame or bottom will work.
Left click and hold on the frame edge and then move the mouse left or right to increase or decrease the distance between the points on the curve. 

Shot 4 shows an increase in the distance between the points and an increase in contrast for that selected range....
I know this one can be very confusing so please ask more questions if needed.

Greg
