Tim,
Theres a segment in the Bowhunters of Trad Gang DVD ...about a double anchor.
Don't be afraid to cozy up to your release hand, and draw your lips back a bit....that will get your elbow farther back....AND, if you can, you may be able to incorporate a 'double anchor' as your thumb base knuckle will slide in behind your jaw under your ear.
Here's a pic....this is full extension....utilizing all I got...with proper alignment, and a double anchor...and you can see, there is no 'scrunched up' look to it.
If what I posted above you can execute,(depending on your body structure) you might gain an inch or more of draw length, and you'll be more inline and set up more on bone structure. You do not 'have' to pull through....but with full extension, you might feel different about a more follow through release. Mess around and see what you can come up with.
What ever works for ya......burn, burn, burn it in.
