Yes, I agree with "The Beav", that one especially should have been fleshed a little better.
Pin EVERY cut, nick, bullet hole etc closed also, no matter how big or small it might be.
If you would modify your wire stretchers with a board on the bottom end, or use WOOD stretchers, you could probably pull most of your coon up into the next larger size simply by pinning down the bottom end.
Here is a couple pix showing you the difference between the wire ones (yours) and the wooden ones (mine).


Trim around the Inspection Window so it is a nice even and smooth edge all the way around. Cut just above where the penis hole would have been and do the same on the females. Make 'em all look pretty much alike.
Here is one other "little trick" for the front legs. Pin them down with pincher-type clothes pins, cut off the excess leg material. Remove the close pins after a couple days. They don't use the front legs for anything anyway...

Comb out the fur in the Inspection Window before you take them in to sell them.
You're doing a Good job!
