Travis,
You aren't doing too bad from what I can see. I think there is an initial setup problem that MIGHT be inhibiting your shot a little. Watch the very first video and right at about 10 seconds, before you lift the bow to draw, look at your string hand wrist. See how the hand is nearly 90 degrees to your arm? Then you maintain that "wrist in, hand out" position for the entire draw.
That puts your draw entirely into your biceps and you will never get a full transfer into your back. That in turn kills any follow through.
If you haven't seen my videos, take a look here:

You REALLY aren't too far off a good shot and I THINK that the change in wrist position may help.
